I'm as happy as anyone to shit on Gamestop, but this worked out fantastically for us. We traded in 36 games going back to Wii/DS, lots of them of middling quality, and got goddamn $380. Holy shit.
Wound up paying of Yakuza Kiwame, grabbed a $100 PSN card to pre-order the Battlefront 2 DE ($80) and have the other $250 sitting on the GS card. Was going to pre-order FF12 just to save some actual cash over my Amazon order but they're not doing pre-orders on the steelbook anymore. Other than that I'll probably just sit on the $250 for a few months for when we get a Switch, that nearly pays for it there.
