I think it's a cute idea, but honestly I don't see how it's going to fool anyone into thinking they've "won" anything. An ad with a discount is called a coupon, and you can get piles of them from the paper on Sunday. Or from your junk mail. Or online. I don't think people will consider them to be valuable unless they're categorically better than what you find in the paper.
