How do I redeem a coupon or promo code?

There are two kinds of code, and they go in different places.

A coupon code activates or extends a plan by itself. You get one from a reseller, in a giveaway, or by email after we verify a PayPal or crypto payment. Open the avatar menu (top-right) → Account → the Coupon code tab, paste the code and press Apply. Your plan activates (or the days are added) right away, and the coupons you've redeemed are listed under Redeemed history on the same tab.

A promo code is a discount on a purchase. On the Upgrade page, press Have a promo code? under the billing periods, enter it and press Apply — the periods then show the promo's discount — and buy as usual. Promo codes don't apply to reseller purchases.

Code refused? Check it's typed exactly (the box switches to capitals as you type — that's expected). "Coupon code is not available or already redeemed." means the code doesn't exist or has already been used; if you think that's wrong, contact support with the code.
