I am not sure if this has been posted before when the photobook question came up, but I thought it was helpful.http://www.photobookgirl.com/blog/my-lay-flat-diy-wedding-photo-book-a-review-of-adoramapix-photobooks/
This particular review is of the AdoramaPix, but there are others on the site. I was looking for a lay flat book that was cheaper. Also, somewhere in there was this link:http://www.photobookgirl.com/blog/august-2010-photo-book-deals-mypublisher-inkubook-mixbook-shutterfly-blurb-photobook-america-picaboo-see-here-winkflash-adoramapix-ritzpix/
It has coupon codes for all of the other places to get photobooks starting with Snapfish to the way more expensive lay flat books.
