as i've written two weeks ago in the playstation nation thread, amazon.de started an offer for ps4 games.
unfortunately, this offer is only for people who preordered the console. check your e-mail account if you preordered the ps4 at amazon.de - you should have received a code.

let me show you which bargains i already shot:
1. preordered the normal ps4 (arrival at launch guaranteed), received a code for Driveclub for 20€
2. ps4 + killzone + 2 controller + camera for 479€ instead of 499€ (price error)
3. got 50€ psn credit because i loaded a total of 250€ to my account (will buy all the indies for "free")
4. 15 months of ps+ for the price of 12 (bought with the money one line above)
5. now i bought AC4, Knack and NFS for 150€
must-have-list for platforms i don't own yet:
WiiU: Donkey Kong
XBone: Dead Rising 3, Ryse
