car tent sale scratch off game winner?

ok so today i got this invitation by mail to go to a car tent sale at the local dog track sponsored by some companies there like wachovia, well it came with a scratch off game i was supposed to redeem there and supposedly i won all three prizes which included gas money,3 nights in vegas, and an online shopping spree
it sounds so fake to me even though it assures people on the bottom that buying a car doesn’t increase chances, purchase not necessary, etc.
so basically i don’t buy it and i wouldn’t wanna waste my time by going over there and not getting anything in return
so anyone who encountered something like this before how’d it go?
thanks

I get those from local car dealers all the time. Usually they say (in small print) that one of the ‘definitely-given’ prizes is something like 2 bucks. If you figure that putting up with a high-pressure sales pitch is worth a couple of bucks, go ahead and go. I usually figure my time is more valuable than that.
