Staples have a new coupon that is valid for 10 FREE 4×8 photo cards. You would need to pick these up in store in order to get them for FREE.
This deal is valid through 11/12. While 10 is probably not enough for holiday cards, but you can always make little Thanksgiving cards or thank you notes.
Check out the cards that I made that my daughter can give her grandparents, god parents and anybody else she wants on Thanksgiving.
