You can buy Coins directly from the Add Guests page, after you have designed your card and added your recipient list. If you do not have enough Coins to send to your list, the blue button in the top right corner of the page will read "Buy Coins". Once you do have enough Coins for your mailing, the button will read "Send to Guests/Recipients"
Or, navigate directly to the Buy Coins page, select your preferred purchasing option, and check out.
If you want more information on what Coins are, please see our Coins FAQ.
