The coupon value will be subtracted from the total amount.
Coupons with fixed amount: Please note that coupons with a fixed amount are bound to a currency. So a EUR coupon will not work for a payment e.g. USD.
Coupons with a fixed amount are also restricted to a duration of one month. So using a fixed amount coupon (e.g. $5) on an annual silver wok will give you the maximum discount for one month of the subscription - $4 in for the annual siver wok.
% - coupons: Not dependant on a currency. Just apply them to a monthly or an annual subscription.
