Quality of books is great. However, we are upset with Groupon advertising of Shutterfly offers. The offers indicate that you will receive each of five books for $5 using the Groupon offer (hardcover, custom, 20 pages, shipping not included.) However, when making the Groupon purchase, there is no mention of "per book" cost. From our experience, apparently, you are paying five times as much as indicated "per book".
