Through March 24, 2010, you can get up to eight different 30-page 5×7 Photo Books for $3.99 each shipped from ArtsCow!
I have gotten prints done from them about a year ago and the quality is very nice. I was impressed. I hope that they have not dropped their standards.
Just create your Photo Book at ArtsCow and then use coupon code 75BKSFEB10 at checkout and it should give you the Photo Book for free with only a $3.99 shipping charge.
