I currently have a Mid-2013 MacBook Air. Somehow, I got a rather noticeable scratch on the display, and Apple will fix it for $500. Truth be told, I wanted a Pro from the beginning, so I'm thinking its time to sell if they want that much. Top of the line Pro is $3200, I'm sure I can find some places to knock that down, but I would like to get it if possible. Anyway, I noticed there's no Swappa for computers. I'm wary to sell something like a Mac on eBay. Are there some good places that are trustworthy to sell a MacBook Air without getting ripped off too much? Besides Craigslist?
