Zynga and 7-Eleven plan FarmVille, Mafia Wars, YoVille promo?

We've already been hearing rumors that the makers of FarmVille, Zynga, is planning roll out items in game sponsored by advertisers. We haven't seen any of these just yet, but that will change in the next few months if the rumor that 7-Eleven items will start appearing in FarmVille, Mafia Wars and YoVille and that the convenience store chain will be releasing a series of branded (and collectible) items in tandem.

FarmVille Freak says the promotion wil start between June 1 and July 15 and will have FarmVille-branded Big Gulp cups and three collectible Slurpee cups. "The pics are tiny and you would need a magnifying glass to see them, but there are 3 slurpee collector cups and a a Big Gulp cup with the sheep on the tractor image from the FV bumper sticker," says the anonymous 7-11 employee who spilled the beans.

Other promo items include the following:

- Seven Select (7-11 store brand) candy ( gummi's ) & Bakery will be focused on Yoville

- Seven Select Chips/snacks/hot foods will be focused around Mafia Wars

- Slurpees/Big Gulps will be centered around Farmville
