I am contemplating selling my Gucci Abbey. I'm just tired of this bag and want something new. The problem is, This bag is about $700 new, and I've only seen them get as high as $400 on eBay. I mean, I know it's used, but it's in perfect condition and I think it's worth more than that. How do I get a good price for it? I have all the things, box, dustbag, cards, receipt from gucci.com. Is this what people look for? What should I say on the listing? Thanks so much for your help!
