Proud member of the Costello's team.

I started going to Ace because a new store opened up near me (Smithtown) and I figured I’d check it out. Wow, I love it. Everyone in the store is so helpful and friendly. The store isn’t huge but it has everything I need. Nice Job you guys! It’s very pleasant to shop in a store like that!

Craig researched all available shovels via Ace Net and found the one I was looking for. Craig called Centereach and they had it and I went there to get it. I wanted to compliment Craig on his exceptional service. I will make sure Costello’s is my first stop for hardware needs.
