From 7-Eleven website :

7-Eleven has team up with your favorite Zynga games to offer exclusive gifts with the purchase for players of Farmville, Mafia Wars and Yoville. We’ll see you at 12 a.m. on May 17 to start redeeming codes for Virtual Zynga items.

Players will be able to buy snacks and beverages whilst being rewarded with exclusive “Mafia Wars” items that cannot be purchased elsewhere. International players won’t be able to participate in the promotion.

Wew.. Even if international players be able to participate in this promotion, No 7-Eleven near me, even I live in one of the biggest city in Indonesia.. Hammer
Bye Bye.. ‘Exclusive’ Item. I hope there is another way to get that ‘exclusive’ item.

Update : For some reason or another Zynga and 7 Eleven promotion will be delay till June 1st.

“Showman Gun” will be the exclusive item that will be released. If any of you guys saw any mafia wars devs with this item, please help to give me the image link. Thanks
