Sold abstracts that away from you. You take a pic on your phone, send it to Sold and they come back with a price they think they can sell it for. If you agree, they'll send you a box, you ship it to them and you get the money. You're not supposed to know how they sell it.

This is drastically more convenient than dealing with EBay, answering emails, making calls, screening real buyers from non-buyers, or going to Starbucks to make a Craigslist deal.
