What can I get at Amazon for .50 cents?!

Strange question, I know.

So I'm ordering the New Rules of Lifting books, one for men and one for women... they're both eligible for free shipping with orders $25 or more, and the two books come out to $24.48!! GRRRR!! I don't want to spend any more than I have to to get that free shipping.

So... what can I get that's preferably weight loss/exercise/health related that is CHEAP? Real cheap. lol

Mahalo nui loa, love and alohas to you all!
