Went to see if they had a product, and unfortunately they didn't. However, A.C. called up another shop about 10 minutes away to make sure they had it. He wanted to make sure I got what I needed, and I'm for sure going to be back. Thanks so much A.C. for the great service and conversation!

Very knowledgeable and helpful. I’d rather buy from him over Home Depot or any of the larger chains. I’m rooting for this guy, one trip to his store and you’ll understand why.
