The listing, FarmVille, YoVille, Mafia Wars gift code has ended.
Im almost positive this code is from a hot dog carton from 7-evelen. Its good for the game Mafia Wars. You enter it at buyearnplay.com and you get a "Sleek Bullet Proof Vest with Attack: 45 and Defense: 23.
Even if you don't play Mafia Wars (like me) this code will still count towards your "punch card thing." Once you get 5-8 codes of differenct product types you unlock all (3) three "UBER gifts"
FarmVille players its 200 FV cash.
Mafia Wars players its 50 skill points.
YoVille its a slurpee machine!
Happy bidding!
