I use Swappa for almost all of my tech buys and sells. It is free to list and $10 for a sell (paid for by the buyer, so if you list for $200, the buyer sees the price as $210). So you just pay shipping (and technically $10 since you lost out on buyer's $10 to Swappa). eBay takes like 10% + shipping. I always forget this until I get my eBay invoice and realize I took huge losses when I thought I broke even. I sell a $300 tablet, I end up with like $245 after eBay fees, shipping, and PayPal fees. Craigslist is good if you're in a city, but it is terrible for rural areas. Sometimes I find good deals on there, but when I'm selling, no one wants to pay me asking price.
