Just select and personalize a Valentine’s card found here and then enter coupon code CEA4299during the final stage of checkout. Keep in mind that you will have to pay shipping charges which start at $1.25 for 1-3 cards and then increase from there. If you choose the “Mail it to the Recipient” option and you’ll pay an additional $0.49 for the stamp. I must say from personal experience, Cardstore has the cutest designs and great quality!
