You can enter a promo or discount code when you buy a treatment in Shop, and when you move to a longer plan with Upgrade my plan. Your total updates to show the discount before you pay.
Apply a code at checkout
- Select Shop, add your treatment, and go to checkout.
- On the checkout step, find the Promo code field.
- Enter your code and select Apply. Your total updates to show the discount before you pay.
To take a code off, select Remove.
Use a code when you upgrade your plan
- Select Treatments (on a phone, tap My Plan), then select Manage next to your plan.
- Select Upgrade my plan. If you don't see it, check under More. This option only shows when a longer plan is available to you.
- Pick the plan you want, then select Have a promo code?
- Enter your code and select Apply. You'll see what the code does before you confirm.
Good to know
- Each code has its own rules. How much it takes off, whether it applies to a first order or every order, and which plans it covers depend on that code. Checkout shows what yours does before you pay.
- One code per order.
- Want to use a code on the plan you already have, without changing your plan length? There's no place in the portal to do that. Message us with the code and we'll check it for you. This includes restarting a paused plan with Pay now: message us before you pay, and we'll add the code to your plan first.
If a code won't apply
It may have expired, already been used, or not apply to your plan. Some codes only work when you move to a longer plan. Double-check the exact code. If it still won't work, message us and we'll check it for you.
