A discount code related to a membership can only be redeemed when signing up for a Premium Membership.
During the registration process, you can select your preferred payment method.
If you have a discount code available, you can enter it in the appropriate section:
Enter the discount code in the designated field and click "Check Code".
The discount will be automatically deducted from the base price. You can then continue with the registration process.
The discount will then be applied to your contract, and you will receive a reduced membership fee.
