I bought a groupon for photobook america and was disappointed to find that 1)if I decide to change types/size of books I have to start all over, and 2) that there is a 40% off sale, so with my groupon I've saved a whole $4. I've not done this before and didn't realize that the definitions for page numbers and 'multiple' is different than in real life. I actually put together 2 books, but they will only let me use the voucher for one. Big disappointment. I've written to groupon to complain.
