One of the things that most bothers me about American advertising is the blatant contempt that companies have for their customers. Check out this picture. They're basically saying either a) that they don't assume that people can understand that 18 is a larger value than 12 or b) that they think people are so stupid that we'll be impressed by a slogan that says, in essence, "this box has more taco shells than a box with fewer taco shells!"
I'm going with b). I mean, they didn't even make the qualification font very small!
