We don't often have promo codes available, but if you do get your hands on one, here is how to apply it.

When you are starting your subscription, look for a Add Discount link on the final page of the checkout process, where you are adding your payment details

This will load an input field that allows you to type or paste the code you have.

Please note: promo codes are valid for a fixed period of time - you will see a message saying, for example, "This coupon is valid for 3 months.". After that period, the billings will renew at full price.
