I also got a PSN code for Tuesday's DLC. Still not sure what I'm gonna get. "Dream On" is the only definite purchase so far. Debating "Walk This Way," "Sweet Emotion" and just getting the whole damned pack.
Gamestop no longer sells $20 PSN cards. At least the one by my house doesn't. I got a code printed on the receipt instead of a physical card. I must say I'm not thrilled about that. It's way easier to lose a receipt than a big plastic card.
