Thru midnight tonight, September 17th, you can get a FREE 20-Page 8×8 Hardcover Photo Book from Shutterfly (or a $29.99 credit towards a larger size) when you use the promo code FREETREAT at checkout.
Just make your book, then be sure to use that special code at checkout.
Note that you will have to pay shipping, which should be around $7.99 — still a great deal on one of these photo books.
Thank you very much for posting this, just sent off my order!
