I just received a coupon from shutterfly that says I can refer up to three friends to receive a free 8 x 8 photobook. I don't know any more details than that (it might only apply to new customers, but it doesn't say that). Email me at hkiesling at yahoo.com if you want me to refer you. I would just need your email address I think. They might make nice guest books or b-pic books or even parent books.
