One of my coworkers walked up to me one day and asked if I knew a place where he could sell his entire N64 collection.
For $320 I got the console with a RAM expansion, 4 controllers, and 40 games. Most of those games came with the case and manual, so they are worth a LOT more than I paid. He also threw in a huge pile of Playstation games for free, some of which are worth close to $50. I'm probably never going to sell them, but it feels good knowing that I would only need to sell 4-5 of my more valuable games in order to make a profit.
