If you're looking to ditch some games, take them in to GameStop today as their new promotion lets you buy any game for only $9.99 with two trade-ins. Basically, your two game trades discount a $59.99 title to only $9.99. So, two games and $10 gets you a new title.
Mind you, they have to be eligible games. The list here shows features some reasonable requests (Star Trek), but they can kiss my ass if they think I'm going to trade in Xenoblade Chronicles. Giving me what's essentially $30 for a super rare game? Don't make me sick my corgis on you, GameStop.
