Paperless Post uses an online currency called Coins. Coins are used to send mailings that use premium card designs and custom options* such as envelopes, liners and logos.
Coins can be purchased on the website or within the app. You can purchase coins through the app by navigating to your Account Settings.

*Not all premium options are available on the app, but are all accessible from the full website on a computer.
