It's a consignment store--so it can be pretty hit or miss in terms of selection. There's definitely some crap here, so be prepared to dig. A bit more grown-up and less brand-obsessed than the Tempe location. Great accessories selection here.
Can't comment on the buying, but definitely seems like some of the other reviewers take a bit of a bruising to their egos during the selling process. Considering the typical outfit worn by the employees here involves a romper, cowboy boots, and a tutu, I wouldn't take it too personally that your Cole Haan jacket wasn't bought by the store. Come here to shop on the cheap, not to sell.
