Free pictures & photo book

I saw this at Freebies 4 Mom. There is a new photo site called ArtsCow and they are offering free prints for new users. It is free to create an account. There is a limit to how many people can get this offer and I'm not sure how many have signed up...so you need to hurry! I just signed up and if you use this link, I can get even more free prints. It looks like you can print 50 4x6 pictures and 50 5x7 pictures every month for 4 months and a free 8x8 photo book (up to 20 pages). I've been using Shutterfly for printing photo books for Emma but I can certainly try another site - especially since it will be free!!
