CVS has photo books priced at Buy One Get One Free starting on Sunday.
There is also a new printable coupon to Buy One Get One Free Kodak photobooks.
So, in theory, you should be able to get up to 4 books total for free! I know this exact offer has happened a few times in the past and people have had really good luck, but remember CVS does not have a printable coupon policy so you may have to adjust your scenario a little.
I would still print it out while it is available and cross your fingers!
