Today only, Cardstore offers any card for 99 cents via coupon code "CCE3301". That's among the best general offers we've seen from Cardstore in recent months. (We saw ten free greeting cards with free shipping in November. We also saw a 5x7" card for 47 cents two weeks ago.) Shipping isn't included; it adds $1. (You can also opt to send it directly to your recipient; postage adds 46 cents.) Deal ends March 8.
