why, you ask?
It's worth $20 in store credit!
I went to gamestop yesterday, and traded in a couple of DS games and a gamecube game for........$72!!!! I was expecting $25!
But it gets better....I paid an extra $15 for a subscription to gameinformer and an extra 10% on the games I traded in... which brought the total on the games I traded in to be $79! subtract $15 from that and you have $64! so I pretty much got a subscription to the magazine and a discount off used games for $8!
I'm pretty happy, as you can see. Now, I need to sell some more games, now that I know that they'll be worth something.
