If you made the free mother's day card from them when I posted that then you already have an account. If you did not and you don't have an account then you will be prompted to make one during check out. (Don't worry no credit card needed!)
Make sure you click the SEND TO ME FIRST option unless you WANT to pay shipping ($0.44) and have them send directly to your recipient!
Seems to work for cards up to $3.99 in value!
