I got an email saying free 8x8 photo book when you use the promo code "SUMMERBOOK" and the offer ends wednesday, I guess meaning 9/12. I used them to create a little book to have around of a bunch of pics of us leading up to our engagement. I can't find anything but last time I used one of these you had to keep it to 20 pages or just pay for the extra pages. The clicky also says if you want a bigger book (8X11 or whatever) it will get you 29.99 off.
Would also work for your engagement photos too (I did this, but used mypublisher at the time because I had a deal from them at the time).
Heres the ridiculously long URL:
