PetVille: Earn 200 Pet Cash by using Pro Flowers for Mother's Day
Aside from their Mother's Day themed set, PetVille is also exhibiting the same offer that FarmVille had, which is a premium virtual cash promotion via Pro Flowers. While FarmVille was offering 100 Farm Cash, PetVille is offering 200 Pet Cash. There's no limit to how many orders you make, and the fine print guarantees that the Pet Cash will be delivered instantly with the first order, and everything afterwards will be credited within 1 day.
In order to access this offer, you need to look to the bottom of your PetVille game and click on the sponsored link of the Pro Flowers ad (see image on right).
