Economy of Scale
How is it everybody understands the concept of Mr. Alan's "Twenty nine or two for fiddy!" and everyone gets that if you buy one book from Amazon.com that you can tack on another one at a reduced rate, yet when we sell theater box candy at Walgreens for 3/$3, everybody assumes that you can get 1/$1 completely missing that the sign says, "or $1.29 each"? If we wanted it 1/$1 we would've said that and not 3/$3. You have to buy all three dork. It's called "Economy of Scale". Buy more, save more; buy one, don't save. *sigh*
