Cardstore.com is once again offering a free card! I love the fact that I haven’t had to purchase a birthday card for months, thanks to all of the free cards that Cardstore has been offering. Getting one for yourself is quite simple. Browse through the collection (and it's a large collection), add a card to your cart, and use code FRIEND12 at checkout. You will want to select the "Send me blank envelopes" to avoid any shipping charges. That’s it! Within about a week, you’ll have a card waiting for you in your mailbox. This offer is valid through August 5th.
