Expensive. $8 for a shirt? $12 for a skirt? At those prices, you can buy something new, or go to Goodwill instead.
As for selling, I can say that I've bought stuff from them to assemble a Halloween costume, but they wouldn't buy the same items back later. Interesting.
But I'll give it 2 stars instead of 1, because I don't agree with others' complaints about the staff. When I went I didn't notice anyone particularly rude, and the girl who didn't buy my stuff back said "sorry" (in a nice way).
