So it's back again (at least at the McDonald's in my area) and memories of getting every single common piece and none of the rare pieces thereby winning nothing are bubbling up. I think I won a few free large fries and drinks and burgers, though.

Has anyone ever won anything substantial?

No, Roll up the Rim is the superior marketing game.

I always wonder if people ever win things .. you never hear about it.
Like the "Win a million bucks if you find the bag of all blue M&Ms" and crap like that.

You think you'd hear it on the news or something, but no.

I don't blame the guy.
My friends and I used to steal the French Fry boxes to get a whole case of stickers.
