Obviously you have to be a bit savvy. I bought Mario and Sonic brand new on offer in Morrison's for £15 and traded it in a month later at GAME for £20 (part exchange). If I'm offered less than half the price I originally paid for it I often keep hold of the game, but really, if you're never going to play a game again, you may as well get what you can for it (though I imagine in a lot of cases ebay would be a better bet than a shop).
