This review is for the new Double Chocolate Mint Sundae at the Costco Food Court. If you're on the fence about the new Mint Sundae, get the vanilla/mint swirl. It reminds me of a Shamrock Shake but not as sweet, and the vanilla rounds out the mint perfectly. The chocolate fudge and the crunchy cookie bits on top are the perfect combo kinda like a deconstructed Thin Mint. Love that Costco has this flavor and color combo in time for St. Patty. For $2.99 it's worth a try. Grab it before it's gone! read more

Not my favorite Costco. For some reason, this is the worst parking lot of the SD locations. Best gas, worst lot. Almost impossible to get a handicap spot, and some of the most irritable shoppers. Endless circling for a spot must really make them nuts, because I've been yelled at more than once. Indoor food court, which makes it more difficult to just get food. Not as much seating as Carmel Mountain, so you may be standing to eat. And a lot of people eat after they shop, so watch out for carts parked everywhere. The rest of the warehouse is similar to the smaller locations, but each has its own layout inside. They don't seem to get the specialized items that some locations do, but they have all the standard items. read more

It's your average Costco. VERY busy, and parking can be an absolute nightmare, but hey, it's Costco, so it kind of comes with the territory. My real gripe, though, is with the young man working the AT&T kiosk who was heading to work on Tuesday at 3:30 PM. Son... I was kind enough to let you in front of me on the freeway. I even let your distracted driving slide because I try to be a decent human. But then you cut me off again, TWICE- on Nordahl and on the way into the Kohl's parking lot and around the backside of Costco. And you didn't even have the decency to let Costco customers cross with their carts to get to their cars. Get off your phone (yes, I saw you on it) and DO BETTER. We all have places to be, but safety comes first. Costco itself? Fine. Parking? Chaos. Driving etiquette on the way there, for some people? Needs work. read more

Had to make a run this weekend. Ended up with some ahi spicy poke which was great! Also grabbed a tray of meatloaf and mashed potatoes for some easy meals next couple days. I'm happy with this location for last at least 15 years. Service is good and selection is the best. Good value if you shop smart. A mistake or two could ruin it....haha! read more

Much better customer service as far as returns compared to costco vista (they should really get rid of this blond manager (looks like she has Botox in her lips) who is really rude and does not embody the costco return policy and is rude repeatedly to customers at the vista store) read more

It's really great that I can get in early....the service is usually very good.....they have a wide selection of items...unfortunately, they have discontinued several items that I like....in most cases, their prices are good...however, checking out sucks...they need to have more lines opened. read more

Recently purchased a bag of red onions from this location and came find out that half the bag was spoiled. Returned the bag the very next day at a different location and found out that the bag had already expired a month ago. Be careful and check for expired/spoiled produce! read more

Picture it- December 21, 2025. It's the Sunday before Christmas, there's a huge storm about to swallow up all of California, and it's the last day of the sale booklet.... Now, I don't celebrate Christmas and I try to avoid all the holiday madness, but I couldn't avoid Costco on this fateful morning. I needed a few regular items. With a solid plan in place, I parked at 8:57am and took full advantage of the executive hour. I timed getting in line JUST as they opened the door- I didn't care that I was all the back by the loading dock. The line started to move, and quickly! Costco employees were prepared- they had 3 people outside making sure everyone followed instructions and no one cut in line. Let me tell you...you don't want to mess with these bouncers! Once inside, everyone (minus me!) made a beeline to the bakery and meat department. I was able to get what I needed in peace, before I headed that way. That's when the mad rush started and I overheard everyone's holiday plans, what they were making, what day, and what they needed. I was able to stay in my Costco zone, game face on, get what I needed, make my way to the cashier (and mind you, there was no one there because everyone was still debating how many pumpkin pies they would need because Uncle Joe was coming on Christmas Day and bring his new wife, and the family hadn't met her yet).... I cashed out, made pleasant small talk with the cashier about Galbani marinated mozzarella balls and went on my way. Cheers to 2026. read more

I really like Costco because I genuinely enjoy the employees there. They are always cheerful, kind, and eager to help. Many times, when I buy too much and my cart becomes heavy, someone will immediately come over to help me without being asked. These are such lovely and meaningful actions. In life, what we truly need is kindness, respect, and the way we treat one another as human beings. I always value customer service and the way people treat others more than the products any place offers. Costco is always clean, spacious, and well-ventilated, with no unpleasant smells. The parking lot is large and convenient, so I honestly have nothing to complain about. I especially like Quinn Arias. She is very sweet and always helps me whenever I can't find something. Her kindness really makes my shopping experience better. read more

Busy San Marcos location! The parking lot is always a mess, and getting in there too. The gas station isn't too bad at times but can be really busy. We hate going here because it's a busy location. But they have all the good stuff. It's just like any other Costco. The lines on a weekend is pretty long. The self check out is long too. Busy times, be prepare to wait. Found out the best time to go! It's a Tuesday around 3pm, there's nobody! The food court is inside, and it's a weird method now. You order on the computer then take the receipt and wait in another line to pick up your order. They no longer call your number. They just need one more Costco in North county on the 15, somewhere between RB and Escondido. read more

COSTCO @ San Marcos Who doesn't love Costco! I really enjoyed stopping by this location, parking was super easy to navigate and find. I went on a Tuesday, so there is plenty of room and not too many people. Sadly there wasn't many samples, but I highly recommend stopping by on the week day to avoid long lines. Great deals as always, I always recommend checking your costco app or online to know what's on sale! Service is great, quick to help you if needed, and selection is good. They were out of the coconut water the 9oz size, but still had the label there, so hopefully that restocks. Other than that, highly recommend stopping by, gas station is great as well, just 4.10 for regular! read more

Costco is great and large quantities of some items or larger items that are at your grocery stores. They have seasonal freshly baked cinnamon rolls during Fall/Winter! So good that you crave them! They have great deals on vitamins and other things at a pharmacy. But again it's large quantities. If it's something you use often then the bulk size is worth purchasing. They have a nice clothing department too. You have to hunt for the larger sizes unfortunately but they have as large as 2XL for men. They have excellent frozen meat, meals, pizzas, etc. Soup. Salad etc... seafood is great too! You can get a day pass to check it out. No sharing membership unless the second person lives with you. Doesn't have to be a spouse. Glasses are great here and they have an onsite optometrist, just check if they take VSP or EyeMed etc. For your car they sell tires! Also Costco travel and other perks! It's a fun place to shop! read more

Costco is a big box store. It's your standard run of the mill Costco and yes they do have a gas station so all your shopping needs will be met at this location. I am sure I went inside to get a few items but a careful later I don't know what happened. This location is neat the freewas so egress is an easy thing. Staff is what one would expect from a Costco read more

Alex with AT&T is a life saver! When I was having issues with transferring my phone data to my new device he immediately walked me through it and helped troubleshoot where I had an issue. He reassured me that he would keep watch of the phone as it was transferring and contact me with progress updates and if any issues occurred. Truly peak customer service!! read more

A well stocked Costco! Every staff member is always so welcoming and friendly. The store itself is pretty easy to navigate too. I will say going through checkout here always seems a bit quicker than other locations, although they are just as busy. I don't go to this location often due to the difficulty of getting in and out of the parking lot, since there is really only one way in/one way out and it causes a lot of traffic. read more

Costco has been asking if I want my items boxed and putting them in the box (mostly). I'm happy with them taking care of this issue despite me not bringing it up to them anymore. The customer service is typcially excellent, but be prepared to wait in a long line if going to the tire center. Fyi: Watch out for the ATT employees. I've been lied to on 3 separate occasions when discussing their service and plans. If I didn't know any better, I would have fallen for it. Verizon was pushed out of Costco for similar reasons in the past and Costco should pay attention to AT&T's tactics. read more

Just your local Costco. It's not always easy to find staff to help and the lines are always long. Good place for gas though. The prices are fair for a lot of what they have here and they have a good selection of this and that. read more

I'm not sure of why the bad reviews. Pros: Friendly Staff Helpfull Staff Patient Staff Cons: None Costco is Costco, it a high volume discount store however I found the staff at this location just a level higher than others. In the door it's a madhouse, I was in a rush and was looking for a few specific items, I grabbed "Danielle" right off the floor, I told her what items I needed and she was so sweet as she took me around the store helping me find the items I needed. Danielle knew exactly what i needed and where to find it. Me not really being a frequent shopper here andc was a little lost. She was so patient in helping me and then walked me up front to check out. Great job and thanks. read more

I have never left a review for a superstore, but after many failed attempts to get in contact with management I will be leaving this review. I have literally called at least 5 times over the course of 2 weeks and no one has ever answered the phone. Impossible to speak to someone. There are multiple RACIST Hispanic women working at this location. It is absolutely ridiculous the way I blatantly see the switch from one customer to the next. The rudeness, and being accused of stealing was absurd!!! This has happened with the greeters, ignoring me, while I greet them and say thank you after scanning the card. This has happened after I paid for everything and for in line and was chased down because chicken was switched out by an employee, and then when she saw she was wrong, threw my receipt back at me. Today I've had enough I won't be shopping here anymore. I am tired of leaving with this feeling!!! It's ridiculous!!!! read more

One of the busiest Costco's I've been too. Coming in the morning means that finding a spot is very competitive. Coming from Nordahl making a left onto center drive 2 lanes. The right lane leads to the gas station and the left leads to the parking area. The layout of where they place products is slightly confusing compared to other Costco's. Still has everything you would need. Can't complain. The food court here is inside. read more

I really want to recognize how incredibly nice and friendly the employees are at this Costco. Every interaction felt welcoming, helpful, and genuinely pleasant from the entrance to checkout. The staff here goes above and beyond to make the shopping experience enjoyable. Compared to the Costco in Vista, the difference in customer service is very noticeable. This location truly stands out for its positive and friendly atmosphere. read more

Today, I experienced racial discrimination at Costco San Marcos location, and I feel compelled to speak up. I was shopping at Costco with my 1-year-old son when the cashier, Patricia, treated me in a way that was clearly different from how other customers were being treated. At checkout, she insisted that I place my cart on the left and carry my baby through the right-side lane alone, saying it was a "rule." I explained that my child is too young to sit in the cart alone and that in all my 10+ years of shopping at Costco, no other cashier has ever enforced such a rule--they have always allowed me to stay with my baby for safety reasons. Patricia refused to listen and said the other cashiers had been wrong all along. After I checked out, I asked several other moms if they had been told the same thing--they said no. I then spoke with a floor manager who confirmed that there is no such policy. It became very clear to me that I was being treated differently, and I strongly believe this was because I am Asian. This experience was not only frustrating, it was hurtful. Discrimination--especially against a parent with a young child--should have no place in a store like Costco. I am sharing this not only because I am upset, but because I hope Costco will take this incident seriously on how to treat all customers with respect, fairness, and equality--regardless of their race or background. I hope Costco management will investigate this incident and ensure no other family has to go through what we experienced today. read more

These new muffins are DISGUSTING and UNSATISFACTORY!! Where are the real blueberry muffins?? These new muffins are crumbly, definitely frozen and thawed before placed out (or at least taste that way), and too sweet. Even the blueberries are not the same. Throw these out and bring back the real ones. Everyone else, DONT buy them. I'm saving you money. read more

Happy to be a Costco member again! Took a few years off. This location is really easy to access from the Escondido/San Marcos area. Has all the usual amenities gas station, food court and shopping. It's a little different now with the card scanners at the front. The great thing now is the digital membership card on their Costco app! Even if you forget your physical card no worries you'll still have access to get in. The staff was friendly at this location, very organized they kept the lines moving quickly. Self checkout line was so long but we it moved so fast we didn't even notice the wait. Selection here is always great. Costco does a really good job of sourcing new items. We plan on getting most of our furniture from here. Pricing is always reasonable especially when you use the coupon deals. Great store and excited to be back! read more

We have loved and always gone to Costco for price and quality. Unfortunately the quality has come under question. We bought a Samsung refrigerator freezer ($2,300+) less than three years ago. We have had techs out 3 times (Ice machine x2 and water dispenser x1) on Thanksgiving morning it stopped cooling. We are outside the 90 day warranty from Costco and we are outside the warranty from Samsung. Spoke to Jeff (manager) and he said it is between us and Samsung. My disappointment with Costco is not because they refuse to stand behind the products they sell beyond their stated warranty time, it is because they are currently still selling this same model, when is notorious for failing and breaking! I guess the take away is purchase the extended warranty and avoid Samsung products. read more

Nothing but good experiences shopping here at Costco! I've been coming to this location for decades and their customer service has always been top notch. Returns are never an issue, and the associates are nothing but kind to us. Being able to bulk purchase things for our home makes it so convenient for larger household items like paper towels, cleaning supplies etc. we also purchase a lot of pet products like the Kirkland Nature Domain food for our dog. I don't think I'd ever stop shopping her read more

I was harassed by a Costco gas station employee while waiting in line telling me to move faster after the car in front of me just moved...Come on, Costco, can you please teach your employees how to provide customer service, and direct traffic from the entrance of the gas station and not harass the customers waiting in line...gas is expensive enough... read more

This review is ONLY for the frozen Asian products. The Mila Soup Dumplings are filled with the cheapest, fatty, chewy parts of the pig. So inedible that I returned the bag. The Bibigo Steam Dumpllng contain decent quality meat, but not much more than a teaspoon of it tucked inside a fat sweet bun. Just weird stuff. I think the Costco buyers of these items have been bought off, or hit their heads. read more

It's Costco so it has a lot of good things, but this location has screwed up two major selling points. 1. The design of their gas station creates a huge bottleneck and it's an absolute nightmare almost every time you go; and 2. The food court has gone downhill. Not only did they stop the combo pizza, which was the best thing in their menu, they continue to push out sub quality food. not a fan of the chicken bake at all and don't even think about trying their new "calzone"...I don't even know if this thing can be called a calzone, it's absolutely disgusting and we could not finish it - imagine the worst hot pocket you've ever had...yeah, it's worse than that. read more

Parked far, but still was able to get what we needed. I have a love, hate relationship with Costco.

I love Costco but they really need to up their staffing. The lines are long, especially for returns. Staff is kind but very busy. Prices are affordable. Large selection of seasonal items at a great deal. read more

I used to come here to shop if I was in Escondido, they usually have a lot of good items, recently the quality went down for some reasons, I was at 2 other Costco the day before, and the seedless grapes were huge, but the one in San Marcos had all small, not sure why, if the delivery truck came down, they would hit here first, so they should get the good stocks as usual, hmmm. Anyway still able to find some healthy choice items like the noodles and mixed nuts read more

I returned to Costco San Marcos Optical a few weeks ago to get my new prescription glasses (frames and lenses) with Wally. We got my wife's glasses last month and they were excellent. We have been getting our prescription glasses at Costco with Wally for a long time now and we have been extremely happy. Again, Wally was absolutely a pleasure to work with. As always, he was extremely nice, friendly, courteous, knowledgeable, patient, and helpful. He helped me pick two beautiful pairs of designer frames to order clear and sunglasses with my new prescription. I picked the 1.67 High Index progressive lenses. Wally patiently did all the needed measurements for progressive lenses and also all the insurance paper work. Wally was simply outstanding! I got both my glasses in two weeks and they are super nice and cool. One pair needed a little frame adjustment and Wally took care of it. Many thanks to Wally and Costco San Marcos Optical for their great customer service! Highly recommend them and will go back there again in the future. read more

Lacking in customer service big time. Went in grabbed a number & while waiting I walked around & browsed glasses (also lacking in selection). While I am waiting this lady walks up and asked pricing on glasses. They proceed to answer her questions instead of asking her to take a number while everyone else waits. When they call my number I have glasses that I want to get the prescription filled so I ask her about my insurance give her my insurance information which is CSP and she says she cannot locate me, but I have to call VSP so I proceed to log into my VSP account the same way she told me she needed to log into my account, which was my name, date of birth and last four of Social Security, which she said she couldn't find me, but I proceeded to log on with the exact same information that she had meanwhile, she's helping other customers and I'm standing there waiting then I tell her that I was able to logon and she still tells me that I need to call VSP for authorization at that point I just asked for my glasses back nicely and decide I will go to Costco in Carmel Mountain Ranch. She didn't even offer to try to check my name and date of birth again in case she could've made a typo which I'm assuming it's probably what happens since I was able to login with my information that she needed. Lastly, she was not very friendly didn't smile once maybe she was having a bad day. read more
