I must say, I am loving all the deals from Cardstore.com recently!
Today only, Cardstore.com is offering up 10 FREE Holiday Cards + FREE shipping! Choose from cards for Thanksgiving, Hannukkah, Christmas, Kwanzaa, and New Years.
All you need to do is select and personalize your cards, then enter coupon code CCN2433 during the final stage of checkout (after entering your shipping info). No credit card info is required. The site is pretty swamped, so be patient. :)
