Make sure you don't get ripped off online

A valuable resource for anyone shopping or selling on eBay, Market Price is a new site that crawls the auction site's recent and ending-soon sales for popular products over $100 (iPhones, laptops, etc.) to determine their min/max, median and mean prices, so you can protect yourself from over-paying for or under-selling something, while knowing when to jump on things that're clearly a steal, quite possibly thanks to having been an actual one.
