This is the 2nd set of sheets I have purchased from Overstock recently that was supposedly high quality that pilled up within a week. The first set, I had to make a special arrangements to get permission to send them back because they won't take back anything opened. Obviously, you can't tell the quality of sheets without using them. Well this set did the same thing and I am just going to keep them and use them for the dog's bed (and I don't mean that in a bad way. The dogs like them!). In the past, I have gotten really good quality sheets from overstock, but I think I am done purchasing sheets from them now. Just too expensive to have them be unusable.
