I always keep my eye on scoopon deals and the last few were through photobookshop and they were great I had 4 done in different sizes the smallest were only $6 for a hardcover and 20 pages. They always have specials maybe join their mailing list??
I also use snapfish - have had no issues. (I like Snapfish because they have UK site too, so for people in the UK I order from UK site and get them to post direct from there).
