Two birthday cards and one graduation card that I gave to people this year didn’t cost me a penny. That’s because I got the cards, which were each worth about $3, for free online. Now I’ve just ordered a fourth card.

Cardstore.com is celebrating its new website by giving away cards through Sunday.

Go to the website and pick out a card, which you can personalize. Go through the checkout process, but don’t forget to add the promo code CCM2336 before you’re done. That code will make your card free. You have the option of having it sent directly to the recipient or to you so you can give it to someone personally.

For more about this deal, or to create your own card, go to www.cardstore.com.
