What Our Customers Are Saying

undefinedMay 24, 2022

Staff was very helpful. They didn't have what I needed in stock, even though the website said that they did. The young man helping me tried quite hard to find it, even going so far as to check the top shelves. After several minutes and looking through a couple more aisles, we admitted defeat, but he said that he could order it for me. He looked it up, put the order through, took my payment, and said they would call me in a few days. He was very knowledgeable and the process was quick and easy. Shopping here has always been a pleasure.

I am a frequent customer and came in today looking for a very specific small bolt and received a very kind welcome and all the help I needed from a salesman named Frank. The value of the sale was about one dollar but the overall value to me as a customer was worth a lot more than that. Thank you for taking the time to take care of me!
