Craigslist. Gamestop will give you about 5% of the value on that memory card probably 10% on the controller, and the games unless they're big deal stuff (rare/high demand) you'll get 20% if you're lucky. If you say had like 2 games, the card, and a pad you may have enough for a DS game. I know little of estarland but I don't recall them being anymore generous really from reports I've had.
