How can I use a discount coupon?

The coupons can be used in the billing information form and they will apply discounts only if the following conditions are met : 

• The coupon is used in the time period when the promotion is valid 
• The coupon applies for the products you want to purchase

After entering the coupon (discount code), if the above conditions were met, you will be able to see the actual discount in the next step of the order process.
