Looked like a good site but after ordering, I am not sure. I was in the clearance sales and ordered a few things. The description of the item DOES NOT tell you that it was a returned item. It doesn't tell you that until you had it into your cart. I didn't notice this until after I finalized my order. I was in a hurry to fill my order to get free shipping. I was trying to finalize my order yesterday but they kept taking items out of my cart, changing the price to a higher figure when I went to go get it back. Ugh! The only reason I ordered was because I wanted the Black and Decker under the cabinet Can Opener for my mom which is discontinued in all department stores. Sears has that item but a higher price and it would have came from Wayfair. Wayfair had a lower price.
