I have used Shutterfly since 2009. I always do hardback, generally do black page backgrounds, and always do it manually...positioning my own shots. I have done seven 8x8 books and nine 10x10s. For larger trips, I would wait for an unlimited pages offer and go up to 100 pages or more. I celebrated years ago when they improved their process to enable gorgeous two page spreads. Since then I have used a few in each book. One of the finest features is their 100% guarantee. I f you find they made a glitch, they do another one free.
