I bought three vouchers for photobooks, figuring to make a book for each of my kiddos. While the vouchers worked fine, it was not until I'd already expended a great deal of time and energy working on the books that I noticed that you CANNOT use three vouchers at once, meaning you get charged shipping three times - no combined shipping. I live literally the next city over from photobin, and the shipping is $8.00 per book. Add to that the tax (which, of course, is taken from the original amount), and these "free" vouchers I paid for are not so free, after all. Since I added a few pages at $1 each, after purchasing all three of them with the vouchers, I've spent more than it cost me to get the vouchers (all three together) originally. These better be some damn good books!
