What an amazing experience! Ordered a grill online, expecting it to be delivered in a box. Not…read moreonly did it come assembled, but the two gentlemen who delivered it also carried it through the backyard and onto the deck! They also moved our old grill down to the ground for us. Truly unexpected, but amazing service!!! Stop shopping the big box stores so we do not lose gems like Costello's Ace Hardware!!!

The service I received was exceptional throughout. I went in needing several things: some loose nut…read moreand bolt hardware and a key fob and programming for my car. The counter person took the time to go through the drawers to select what was required. The store manager, Michael, handled my key fob. It was done very quickly and professionally. It was obvious he has had considerable experience working with these. I was recommended I use this store. In looking up the phone number, I accidentally called another local store with a question about my key fob. I was treated very abruptly and received rude responses. The person at that store couldn't be bothered to give me the time of day. Calling the Mercerville store was a completely opposite experience. I intend to use this store for any and all my future needs.

I wanted to return an item that I had purchased more than 90 days earlier. A store manager told me…read morethat I would need to contact Lowes headquarters, which I did. They approved the return and said I would get a call from the store to bring the item in. I waited several days and when I did not get a call, I went to the store. Although there was no communications from Lowes headquarters, Erika was able to assist me and the return was issued. I greatly appreciate her help.

Instead all I was was able to find out was the person who could help me was out to lunch. Before I could ask anything else, he hung up the phone. This was a very disappointing experience since I ordered my dishwasher at the end of August and due to circumstances beyond my control have not yet had it installed.

Joey Hendershot helped my family in such a big way. My mom is 77 and needed to have her porch repaired immediately. All I can say is THANK GOD for Hamilton Building Supply and Hamilton Building Supply should join me in THANKING GOD for Joey Hendershot. It is employees such as Joey that are so courteous, knowledgeable, helpful and professional, that keep customers coming back. For me to be posting this message all the way from California should let you know how grateful I am about the service Joey provided for my New Jersey family members. Thanks Again

I moved to the area somewhat recently and love this store, Rick and Bonnie are always very pleasant…read moreand extremely helpful. My experience with them started with a need for something minor but in a hurry. They are always well stocked with very reasonable pricing, plus the availability to outsource some other services. I prefer the mom and pop shops over the big box for most things, especially when you know what you want, to get in and out, and not deal with crowds, plus you support your own neighbors and community. They always remember your face, even in my case with often long times between visits due to surgeries and mobility issues. Always willing to go the extra mile and make their customer's day better than when they walked in. Services you really can't get at those big box stores!

I was annoyed that Yelp kept prompting me to review this location, I've been here many times. But…read morethey were right, I had overlooked it. When I was doing a major remodel I had to visit many home stores, this one just got lost I guess. My recent visit was for a few general items, all of which they had and at decent prices by my reckoning. In fact on one visit I went elsewhere first only to come here for the needed item. But I think what surprised me most was the credit card offer when I went to check out. Sales are rare here so it was an opportunity for me to save a few dollars, $25 to be exact! I probably won't use the credit card much, but who knows, maybe a small home improvement project this spring? In the past I've gotten less decorative home improvement things here, but also some quality floor lamps and I think my medicine cabinet. I've always found the customer service to be good, and if you don't sneak in an exit you will find a greeter able to assist you in most cases. My one negative impression would be their lack of cashiers, they are actively encouraging self checkout. With so many items in inventory it can clog up the process when a few folks are having issues with the register. On the sales floor there does appear to be enough help.

Except, for some reason in their Robbinsville store (which is a haul from my house, btw.) What wormhole have I fallen into, there are actually people available to answer questions and point you in the right direction. Maybe I'm hallucinating or I've just been the unwitting recipient of a few too many concussions but whatever it is, I don't want to wake up. An easy five stars.

That said, if you're not framing a house in your spare time or building in an earthquake zone, Harbor Freight is just fine for the amateur handyman and weekend warrior. Their tools are certainly less expensive than the big box boys and should do the trick for most jobs. Just understand the limitations of what you're buying. If you're one of those people that just has to have the best tool for every job, I salute you. For everyone else, there's Harbor Freight. Four Made in Cambodia stars.

They'll gleefully shrug and tell you it's "out of order." Plan to quickly clench-walk 100 yards away to a supermarket in the same run-down strip center. When the emergency is over, take your tool-buying business elsewhere. There's a nice Harbor Freight up the road in Flemington, without an atmosphere that reminds you of Fallujah after sunset.
