Coupons are automatically applied when you check out using an affiliate link. You can also apply a coupon code on the confirmation page during the checkout process.
To apply a coupon code or a referral code, either click the affiliate link (if one is supplied) or enter the coupon in the appropriate field on the order confirmation page (the last page of the checkout process) and press the “+” button to apply it. You will see a green banner at the top of the page indicating whether or not the coupon has been successfully applied.
Please note if purchasing a prepaid plan, refill credits will not affect the initial price of your order. Rather, it will be applied to the first paid refill after your prepaid items have shipped.
Coupons can only be applied at the time of purchase. They cannot be applied retroactively after your order has been submitted.
Your referral code cannot be applied to orders placed from your account.
