Easily sell, recycle or dispose your stuff.

Really love this concept. You take a photo of stuff you want to get rid of. Gone then shows you how much they can sell it for. If you want them to sell it, they'll send you a box to send the item to them. If they sell it, they'll send you a check. If they don't, you can choose to donate the item. It's similar to eBay Valet, which launched this week.
@geoffreyweg found this app via a Facebook ad and came back here to see if there's any more reviews about it. Seems like a brilliant product, has anyone successfully sold anything with it? How did it go?
Hm. Bringing the consignment store model online. I guess I always thought peer-to-peer was the natural evolution of consignment, but having a middleman is still convenient.
