Michael Phelps' Facebook page is offering a FREE code for an 8x8 hardcover Shutterfly photo book. They are only available through tomorrow, so be sure to go and grab yours! They are a $29.99 value and do not include shipping - but shipping is only $7.99.
I used these codes last year to buy up a bunch of photo books for my parents, inlaws, grandparents, and grandmother in law, and they turned out BEAUTIFUL and were a huge hit. I definitely recommend.
