1. Redeeming discounts when opening a new account
If you open an account and enter a discount code for a reduction in the account fee, this will be offset against the account fee for one year. If you have a code for a trial month, you start with the free trial month and only then will the fee for the following 12 months be charged for your account model.
2. Redeeming discounts with an existing account
If you already have an account and receive a free month, e.g. because you have referred a friend, this will be added to you after the billing year.
