If I use a coupon code (for example, for 1 or 3 months) and I buy a yearly subscription, how does the discount work?

If you buy a yearly subscription with a coupon code, the payment for those months will be deducted immediately from your total fee. This means that if you select the yearly amount of 264 euros, and use a 1 month coupon code, you will only be charged for 239 euros (saving the 25 euro monthly fee).
