The gas station guys are creepy. They walk around looking into windows at drivers. They stop next to places where women are getting gas. They try to look busy, but are doing nothing but leering. read more

I was trying to get a membership at Montclair location today at around 10:49am but system apparently went down. I asked a kind female employee who was at the exit area checking receipts if she knew when the system would get back up. Mind you, none of us customers were yelling or complaining at this time, we were like oh shucks. The female employee asked her male coworker with glasses who was at the membership area and he was very snarky responding to her with, "I'm not corporate." I felt that was very unprofessional of him to speak like that to her in front of customers and he could have been nicer with his response such as "No sorry, I'm not sure when the system will get back up again, I apologize for the inconvenience." The female employee even apologized to me but it was her coworker that needs to be retrained on how to speak to people especially with the tone he used. read more

The employees at this Costco are rude! It starts at the entrance and continues to the register. My brother had his leg amputated about 6mos ago and recently had a triple bypass. I pulled up in front and helped him out of the car to get a mobility scooter, unfortunately there were none at the entrance so he asked the lady who scans your card at the entrance if she could ask one of the Cart Attendants to retrieve one of the scooters from the parking lot and she told him that is not my job! We had to wait 30mins for a mobility cart to be returned with no help from employees or manager. Everytime I go to this Costco the Cashiers have no help to box items in your cart and are rushing to the next customer while I am still loading my own cart and annoyed and rude that I'm taking too long! Am I the only one that experiences this poor Customer Service ?! Also my last experience at the optical dept was terrible, the employees are rude and unhelpful. It is worth my time to drive to the Costco in Rancho Cucamonga on 4th street for better Customer Service! read more

I know big box stores are under huge pressure to de-skill workers and reduce workforce, but today was a bad enough service experience that I will reduce my business with Costco. Monday morning, huge lines halfway back to the end of the store. I was in self-check. At one point, I scanned an item ans it signalled a problem. The Costco minder came over and put them item in manually and righted the system. I finished up and paid. Zero help with heavy items. On my way out, the checker at the door realized a cheese hadn't rung up. I had to wait like a criminal at the door until a guy came up with a scanner. I thought I could pay for the cheese that the minder had not successfully entered, but no, I was supposed to go back in the store and wait at the back of another line with a cart full of things I had already paid for. Presumably, I would have to have everything refunded and re-charged to my card and spend the better part of an hour for a cheese? Come on! Costco can do better and hire more people. read more

So I pay for my food at the "kiosk" now.. so I'm thinking when I get in line, the line is going to go fast and I'm gonna get my food so I can go !!?? when I get in line, I noticed that the line to my right is going much quicker and when I get to the front counter, the lady says this is the line to pay cash???? So I'm like why don't you guys have a sign??????? So I talked to Brian the head honcho guy there and of course it's always something about "we're working on it".... Right.... read more

This is my go-to Costco when I am visiting my Mom. Whenever she needs me to pick up something for her, I come here. This Costco has excellent selections and friendly service. I never have any issues with the staff here. Their food court is actually outside instead of inside. Perhaps this location doesn't get as much wind as other Costcos... not sure. Parking is a tad tight here... they do get really busy so you may have to park farther out. Funny, this location used to be a Kmart when I was in my teenage years back in the 1990s. Not sure when Kmart got demolished and got turned into a Costco... hmmm, maybe Google may know LOL. Happy Costco'ing! read more

I try to come here early right when they open if I want to avoid the lines. I like that this location is close and convenient to me. Gas lines are not too bad, weekends, do get pretty busy. read more

Food court employees are always yelling at people like they are scolding a bunch of 3rd graders. They need better signs. If you want 2 lines, then add a sign "Two lines". Today I got yelled at because I was in the cash line and not the prepay line. There were NO signs to distinguish between a prepay line and cash line. Stop yelling at your customers! read more

made a phone order for two whole pepperoni pizzas and the worker told me it'll be about 10-15 min. I thought it was weird that they didn't ask for my number or name for when I get there but it's my first time doing a phone order so I just said okay. I get there and wait at the pizza window for 10 min and the guy comes up and I tell him that I called 20 min ago for a phone order and he tells me I have to go wait in the regular line and order there and then wait for the pizzas at this window. I get in line already annoyed because I spent 10 min waiting in this line and then spent another 15 waiting to order and then another 10 min to wait for the pizza. Overall annoying experience ordering over the phone, you wait the same amount if you were to just order here so I recommended doing that read more

I've been a Costco customer at Montclair for 25+ years. I mostly get gas, but on a regular basis. The best thing they ever did was direct the flow of traffic to the gas station through the parking lot. Recently, all of the directional stanchions are gone and it's a flipping free for all. PLEASE, PLEASE, PLEASE put them back. I've almost been hit 3 times in the last 2 visits! read more

I love Costco, but the customer service at this location is trash. I know they have a new CFO that is cracking down on things such as using the food court without a membership, but the way one particular customer service associate treated a 15+ year member is as inexcusable, and embarrassing. Imagine treating your customer service job like you worked for Homeland Security. That's how I was treated when I tried to replace a missing card. That particular associate asked me everything shy of my social security number. My mom's maiden name. Her address. My husband, who has a separate account, requested to put me on his account. I had to show proof that we even lived together, which meant showing my AAA payments on my phone. Super uncomfortable with that. Either this guy or the new CFO are both giagantic douchebags. Super shitty Costco experience. read more

This review is specifically for eye glasses from the Costco Eye Center in Montclair. Service is excellent! Friends have been telling me so for years and I finally can confirm. Good prices, good quality, fast turnaround, and great service. read more

Tmobile girl or whatever started low key laughing at me for some reason. I guess it's because i got a cart that was squeaking and the employees waiting for people to get that cart on purpose. The immaturity. Some of y'all just need to grow up... i ditched the cart went to go get another and saw the same cart, someone else ditched it also. Just went to buy 1 bulky item here. Also, the parking lot and street ways here are crazy. People don't know how to drive in this location and blaming others for their mistakes (whether they doing it deliberately or not, once again, crazy). Ive seen accidents that have already occurred inside the parking lot. HOW?! And people don't follow the lines exiting the parking on left turn street light and end up blaming you for their lack of driving skills. People not trust worthy here, also very weird. be weary... read more

This place is really a messed up place with most workers last week I came to renew my membership I was waiting in line o start noticing a male worker checking receipts and the one thing I notice is all the colored customers were getting their items checked thorough every single item but every white customer all he did was look at the receipt and let them go in their merry way didn't even look in their cart this guy had the nerve to do this really messed up. And today on this day I came in tkk ok get a tire patched it was 4:54 no cars in the bay they weren't doing anything asked if they can patch a tire cause air was leaking they straight out told me no can't do it cause they close in six minutes and I was like ok in six minutes but your still open so I said whatever I went down the road to Firestone got there and asked them after closing hours and t ok my surprise they said no problem big shout out to Firestone on central next to the 10 fwy forget this place Costco honestly it's trash sorry Costco but ain't worth the disappointment read more

Costco always has what you need and there's always something new the people working the self serve aren't very friendly. It's probably easier to go get checked out by a person and going through the self-serve they're always rude not very helpful but I still love Costco. read more

I always love coming here. I don't have a Costco card anymore for now. I was able to get in because my Momma Pat works here as one of the sample people, but we came on her day off. This store is always clean inside and out. I came here to get only 2 items if they had them, and walked out with four! I was able to get the Champion 5 pack of underwear and they were a great value as it was $4 off sale on these!!! Going through the store, we got many free food and drink samples, of course. So the 2nd item I got was a pair of black Skechers with thick bottom soles. These were about $34 not on sale, but they had my size and color. So I had to get them anyways. That was all I needed. However, the two other items I got were thick plush king blankets. They were about $16 each! Another great value. So now we will both have big and warm blankets just in time for start of winter, December 22nd, and Christmas, December 25th. To finish off the perfect Costco trip, we had chocolate ice cream sundaes at the food court outside. By the way, we came here on a Tuesday around 1 pm. Was not as packed as usual. Great experience as shopping is not my gig. Thank you Momma Pat for the access and good times!!! read more

Food court server named Paulie is very rude, switching to Sam's for many reasons but today's rude service really turned me away from Costco. The Montclair location hired the most rude employee. read more

Always have good deals and a lot of selection. Mia at the front register made my whole day.

Johnathon at car tires / batteries sales department, by far the Best service I ever received in Rancho Cucamonga Costco location ( I frequent Montclair, Fontana tire area in the past 3 months) At this location I observed Johnathan's multi tasking between a customer on the phone while also helping another customer ahead of me . He acknowledged anyone who walk in the door with " I will be with you shortly ". While still on the phone assisting his customer. Johnathan's customer service skills compared to the two other locations I visited were superb. ( Costco should have Jonathan train those other guys at the other tire locations ) He welcomed me at the counter and thanked me for being patience, He is professional and polite . read more

Costco Wholesale - Asked for half cheese/ combo . Ok??? - Wholesale Stores Near Me - Montclair, California

I have been a Costco member for a long time now and I use the self checkouts all the time. The employees that work at the self checkout are getting more rude all the time. They look like they are miserable to be there. One guy today didn't say a word to me when I was talking to me. In fact he didn't even make eye contact with me at all! If these are the kind of people they have working there, then I might think twice about shopping there!!!! read more

This Costco is not a problem it's the rude employees that make a store like this low in reviews. Savannah in particular gave me and my an entire family an ugly attitude. She took the cart from my mom and as my mom was going to follow her to the check lane she yelled at her to stay in line. She then dropped the strawberries while putting the items on the conveyor belt and I guess this just set her off because she proceeded to tell the customer in front of us if only they helped. You yell at us to stay back in line but want us to move to the check lane and help? To which I did offer help and she answered I'm already done in a rude tone well motioning me to back up. I never leave reviews but this is just very bad customer service. read more

Way to GO, Cost-CO! I'm so grateful this location is exactly a 10 minute drive from our home. They are always perfectly staffed, fully stocked, clean, and efficient. The parking lot is massive and wraps around both sides of the entrance. This location has a pharmacy, optometry center, bakery (including custom orders), outdoor cafeteria (for the classic $1.50 hotdogs, pizza, etc.), auto center, gas station (ALWAYS busy), and much more. I'm bummed Costco took away their physical photo centers because that was extremely convenient, but you can still access these services online (though not as quick). A few tips: - A 24 hour notice is requested for ordering sandwich platters, cakes, etc. - The bathroom is located at the front of the store to the very left corner of the check-out stands. - If you see a unique item you like, buy it! Costco does not always re-purchase specialty items, especially if the vendor is not willing to negotiate on the price with them. read more

This review is strictly for the lady who takes advantage of the workers who hand out the samples . They're third party workers . She was super rude to them in front of me and the customers ! Worker expressed herself of being overworked ! The lady she didn't care and told her to stop complaining . My daughter knocked down the signed that was hanging for dear life . Which i had picked up while waiting for the sample and she sticked her arm between us to pick it up which i was going to do anyways . She has red lipstick and Mexican dark lady . She needs to be removed . Or re trained read more

We have been shopping at this Costco for a long time now. The staff is friendly and helpful and the store is always fully stocked. However, there are some major concerns about the freshness and quality of their food. My husband came home from Costco yesterday and there were two major issues. The first is that he brought home the famous rotisserie chicken and it was raw on the inside - huge issue. The second is that he bought a two pack of Dave's bread and it was long expired - 12/8/23 to be exact. So the bread is almost one month past expiration. The last item that was of concern was my carton of brown eggs. There was no date on the carton, so I decided to check if the eggs were good. I placed an egg in a full glass of water and it began to float - which means the eggs are old. Because of these issues, mostly because of a raw rotisserie chicken, I'm thinking of switching to Sam's. read more

The Costco in Montclair is a Good Place to Shop for quality products. But one thing that stood out on this particular visit today, ( Busy Friday Afternoon) Rosemary and I had 2 shopping carts of products, and waiting in a long line at self checkout. When a young man came out of nowhere, with a first phone, asked a few questions and started ringing us up. Then instructed us to continue and that the self checkout would have our transaction totals and ready for payment. And sure enough it did . Many thanks to "Mr Ezra " for taking the initiative and helping expedite the process. Good job Ezra and Montclair Costco staff. read more

This is a hard one. I really like going to Costco, I normally go to the Chino Hills location. I was in the area and decided to drop by and get some groceries. This location, is a mess, when you ask employees where products are located they act like you are bothering them.....one guy told me I don't know- you need to look for it. I look at him like can you get on the walkie-talkie, he walks away...wow. Never again will I go to this location, Chino Hills is much better, management needs to instil positive attitude to there employees, they act like they hate their job. read more

I've concluded my search for the worst Costco in SoCal... Congratulations, Montclair Costco! You have the worst traffic and parking lot configuration. Cheers for that. You have the most obnoxious customers. Bless their little hearts. Montclair sales tax appears to be just as high or higher than LA County. Quite an accomplishment! I hope your employees are earning hazard pay for this. The entire warehouse needs to be ripped out and rebuilt - this time with a parking structure and the gas station moved back away from the street (thanks for backing up traffic all the up onto the 10 fwy). Runner-up goes to the Alhambra Costco. Honorable mention to the Downey/Pico Rivera Costco. Well done. read more

I appreciate the familiarity of Costco. We were in the area for a few days and stocked up from here. I did partake in some of the samples which were good and resulted in some purchases which were not planned. The strategy works! read more

Not a bad Costco, but really busy. Huge parking lot but can be hard to find spots, read: don't go on the weekend. The line to the gas station unfortunately backs up into the first entrance which restricts getting into the parking lot. The good though is it's pretty clean, several checkout lines which helps checking out faster. Plenty of stock with items we don't get in Northern CA. All in all it's what you expect from Costco. Have not eaten at the food court and it's always packed so it does appear people seem to enjoy it. I do agree with other reviews, it's dirty with trash everywhere. It's as if a lot of people just don't throw away their trash. read more

Michelle R&Associate of the month at the self checkout, Both associates we're rude!

I was trying to ask whoever was in charge why am I being singled out to show my members card?When I already showed it at the entrance I spoke to manger Victor and he brushed me off with let the member mangers explain to you and left me standing there .After speaking with member manager (Jennifer)and her stating that it's a privilege for me to shop at Costco so them asking me to show proof of membership twice comes with it .Lol ... I like shopping at both Costco and Sam's but after this I rather eliminate my Costco Executive membership completely!!!! read more

This location is super busy, but what costco location isn't ?! This location is very clean and they offer Clorox wipes to clean the carts . Costco is a big box store with some really good deals if you like buying bulk. Last time I was there they had plenty of toilet paper and cleaning supplies. Gasoline at this location is also cheaper than other non member gas stations. Membership prices go up almost every year , so call ahead if wondering . read more

This location is weird to me mainly due to the employees. I had a bad experience with one guy taking up the cashier's time discussing weekend plans and sorting that out while I was standing there waiting to renew my membership for five minute too long. He didn't have his name badge on and he kept telling the girls at the exit that he would help out but he's off the clock. Later I was leaving self check-out and saw him working in the Optometry section selling glasses and he had his name tag on, his name was Jay. Same day, I'm at the self-checkout section with my sisters, we're passing items to each other to scan and all of a sudden a guys comes over and creepily scans our water at the bottom of the cart. I thought it was weird he wouldn't tell us he was doing that, but let it go, but then he started scanning other things in our cart and not saying a word and avoiding eye contact. I thought it was called self check-out but here this guy was, checking out our items for us. Anyway, communication is lacking at this store between employee and customer, but the employees seem to communicate well with each other. Don't go here, it's a weird vibe. read more
