In desperate need of getting rid of some clothes (and after many attempts to sell/trade online), I decided to haul a bag of gently used clothes to Kind Exchange after thorough research. Ideally, I would've hauled it to Common Sort (25% cash back and 50% store credit) but considering the distance and the lack of Metropass, I was unable to go to either stores. Kind Exchange was the next best thing considering proximity from where I was.
I dropped off my bag sometime at noon and received a call from them about two hours before the store closed. I was happy to find out that they decided to buy 5 items from me. Instead of getting cash back, I decided to do store credit instead. I might as well, considering it would be more value than the cash, which was going to be spent on buying clothes anyway. I ended up with a cute sweater and a black liquid skater skirt I have been looking for ages.
They are extremely picky with their clothes so be ready to haul back everything in case they say no unless you are willing to just donate them. You won't get back on much at all. The value that they were going to sell all my items were for $100 and I got $30 store credit (20% cash back and 30% store credit). So be sure that you really don't care about the clothes you are going to bring because if you think you are getting back at least half of your investment, you are mistaken.
I personally liked my experience here because the employee who was helping me was very nice and outgoing. Apparently she works at their Roncesvalles store, so I hope the regular employees are just as nice.
