SeeHere is offering a great deal through the end of December. Use code: 25cards to get it. SeeHere is offering 24 or 25 FREE 4X6 photo cards. The only thing you have to pay is shipping charges. Shipping is $4.99 for 25 cards. And shipping is only $2.49 for 24 cards! Unless you really need 25 cards, I'd go with 24!
I just received my photo cards in the mail and they turned out great!
