Through 4 PM on Sunday June 10th, Shutterfly is offering a $10 off any $10 or more purchase. Just use the code SHARE10 at checkout to redeem this offer.
You will still need to pay shipping, but there are several options including their 5x7 softcover Photo Book that will get you a great deal for $5 or under including shipping.
I've order MANY things from Shutterfly and have been very pleased. Whether I'm ordering photo books, photo calendars, photo cards, or just photo prints, the quality has been good and the service prompt.
