buying: this is a total hit or miss. sometimes i go in and i find a handful of stuff that's at just the right price. other times i go in and the only good things are the "new" things they have hanging with the resale items. and those are NOT priced well. i might as well go to urban outfitters down the street for those items! it's weird because you'd think they'd have a better selection and that i'd find more seeing how picky they are when they buy back your things.
selling: they are extremely selective with what they take. a lot of the time i would just end up donating the rest of my items even though i know it's worth trying again at another time or season. at that point it's more out of convenience so i can empty out my crowded closet and not have to bring the bags of clothing back home. i've been more lucky with selling than buying lately. i bring in a lot of items that are in great condition or even new! i definitely recommend standing there while they view your items so that if they have questions you can answer them. i know that's helped sold an item many times in my case. they will ask how much you bought it for or where you bought it..and if it's a "boutique" item...they all of a sudden value it more.
i still drop by every once and a while. i'm a sucker for resale stores and always hope to find that perfect thing at the right price....but unfortunately haven't found much there lately.
