Youre team did an excellent job as usual. The sheet metal and grommets arrived in excellent condition and were very well priced which I appreciate. Thanks again. Doug

I just ordered four very tiny items for a couple of bucks and you treated me like I ordered much much more. The order got to me in just a few days and all I can say is your company is at the top of my list. Thank you very much. Stan

Brittany was attentive to our needs. We had to source some other products you didn't have elsewhere. We would have preferred to place an order a one place. Will come back and order another time.
