Dan's Discount Windows & Doors

I bought 2 steel doors for $7 less than Home Depot. Asked guy @ counter if I could exchange if size was off & he said "yes". No mention of restocking fee until I tried to exchange one of the doors for a slightly smaller one. Was told that I had to pay 30% restocking fee for a straight exchange & that it's noted on my invoice. True it is on the invoice, but the customer doesn't see that until the product has already been paid for. All exterior & interior doors as well as all windows in my house need to be replaced. I can say for sure that I won't be buying them from Dan's Discount Windows and Doors and I suggest other people steer clear as well.
