Coupon codes and sales

On Plan and billing, type the code in the coupon box and press Apply. The prices on the page update right away and the discount shows on your invoice. When a sale is running, the old price appears crossed out on the pricing page and the discount applies by itself, no code needed.

Some discounts apply to the first payment only (the next renewal is at the regular price), others to every renewal; the coupon's description says which. A code can usually be used once per account.
