Missed their Chance?

Today, I won a bottle of Sprite. The news of my “wild prize” was printed on the underside of the cap, and I only saw it because I dropped it on the floor and took a good look at it as I bent to retrieve it. I threw the cap out anyway, since redeeming it is such a pain, but then I started wondering - how many people miss winning $10,000 (or however much) because they didn’t look under the cap? Those soda companies must’ve done some research on this…

This is probably true about a lot of things such as lottery tickets, coupons, warranties…
