Well see, not everything you order are supposedly- supposed to ship {Its pretty much a "chance" in getting a prize}.
And usually the bigger prizes take a while longer than other prizes to ship [I.E: Cards could take one month, while a Vista Ultimate could take 3 months].
*Theres a chance on getting prizes, whether its getting them, or not getting them. {Its all upon CB's decisions}. I wouldn't be worried, though, if it were ordered 3 months ago, then yes, you should be worried. But, if it were ordered 0-1 month ago, you shouldnt
