Prices are beyond outrageous, the staff has absolutely zero knowledge of their products (which are very poor quality these days - and the store does not stand by their products), and no proper understanding of service, not to mention a lazy, very unpleasant attitude, and no regard for longtime loyal customers who now are former customers.

First, I bought weed b gone...oops wrong one, my fault. I saw the brand, wrong size. Second coupon $5.00 off a $20 purchase.....but wait......don't buy green egg woodchips (****) That's what comes up, an asterisk which means that it didn't qualify.....what? So now I was 2cents short. But thank you to the wonderful cashier, she did the right thing. So.....5 stars to the cashier 1 stars to a store which makes you jump through hoops to use a coupon. Come on now! So, average 2.5 stars, I gave 3 because of the sweet cashier!

You will probably need help from the clerks in finding it, as the aisles are overstocked. In that sense, it feels like an old-skool hardware store, much different than shopping at a home depot. However, be warned, these guys don't care what you're building and their recommendations are half-hearted. . . . they just want to go back to their prior conversations and bullsh*tting: A rush to get you out of here, so old-timers looking to make smalltalk may be disappointed in way of the "experience" of buying things.

I had a mixed experience at Costello's Ace Hardware in Nesconset…read more The woman at the paint counter was excellent. The store was busy, she was helping multiple people at once, and she still provided great service to me while also taking care of the gentleman waiting for his paint. She handled the situation professionally and was very helpful. The checkout experience was very different. I went to purchase lawn seed that had a yellow sale tag, and the tag also indicated Ace members would receive an additional $1 off. Based on that, I expected it to be a good deal. There were two people behind the counter. One person was helping another customer, and the other man behind the counter yelled "next customer," which felt unnecessary given the small size of the store. Maybe he was having a bad day, but the interaction felt dismissive from the start. When I approached, he asked if I was an Ace member, I entered my phone number, and he proceeded to charge me $11 over the sale price. I pointed out the yellow sale tag on the shelf, and he rudely pointed out that it was last week's sale, which could be seen by the 4/28 date in tiny print. Today is 4/29, so I understand the sale had ended, but the sale tags were still up. Honestly, I did not notice the small date, and I relied on the sale sign that was still posted. He did not honor the sale price and seemed annoyed that I even asked about it. I always thought Ace was more customer friendly, but this experience was disappointing. A simple acknowledgment, explanation, or courtesy adjustment would have made a big difference. Based on this interaction, I guess I will have to shop elsewhere.

Young people should absolutely not be working here and neither should people who have absolutely no experience or knowledge on the products sold here. I came in here today and asked for help with a few projects I have at home. A young man helped me and he was nice but kept rushing through helping me and also didn't seem to know what to look for to actually help me find what I needed, he just pretended he knew what he was doing. He also didn't help me find specific things I needed by assisting me to the correct part of the aisles. He rushed me when I was paying as well so much that when I got home and looked in my bag ready to start my projects he didn't pack half of the things I bought. On top of that, he gave me the wrong screws. I WANT MY MONEY BACK.
