Through this Wednesday, June 20th, you can get a 4.5×6 Brag Book for $0.99 + $2.99 shipping at Walgreens.com! Use coupon code BRAG99 to get the deal (regularly $6.99). My guess is that this is limited to your first 20 pages, and that additional pages would be a surcharge.
Just a tip – before you spend hours making a photo book, test out the coupon code to make sure it’s working. :) It’s one their advertising on their site, so it should be fine, but it’s always a good idea to doublecheck before investing too much energy into creating a book!
