Tiny Prints is offering a FREE thank you card today. I'm really not the thank-you card type, but when I saw that pretty orange bouquet card, I had to have it (free)! I stuck a cute quote where the "thank you" part was supposed to be on the front of the card, and I'll plan on sticking it in a frame somewhere. :)
Use the code TYOPRAH and this card will be absolutely FREE (but they do still need your credit card info). You can have it mailed to you or to a recipient. If you mail it to yourself it's free, but if you mail it to someone else, it costs the price of a stamp.
