You can choose to give a one-time gift or an automatic recurring gift. To setup a recurring gift, you will be asked to login to your existing account or create a new account.
Logging in allows you to save your billing name and address information so you don't have to enter it each time you visit. Logging in also in allows you to review your transaction history and manage any automatic recurring gifts.
For your safety, credit card and bank account information are never stored. You will need to enter these each time you visit.
