# How do customers redeem a promo code at checkout?

> What families do to enter a discount code at storefront checkout.

<Note>
  **Must know**

  * There's no customer-facing list of available codes — families type the code in themselves, so share it with them however you run the promotion.
  * Customers can enter more than one code, but only **one discount applies per cart line** — codes don't stack on the same item.
  * Each code gets instant accept-or-reject feedback before payment, so families know it worked.
</Note>

Codes are entered on the storefront checkout page, in the order summary. Here's the family's experience so you can guide them.

<Steps>
  <Step title="Find the Discount Code box">
    On the checkout page there's a **Discount Code** field with an **Enter code** placeholder, next to an **Apply** button.
  </Step>

  <Step title="Type the code and apply">
    The customer types the code (it's uppercased automatically) and clicks **Apply** or presses Enter. Uplifter checks it live against the cart.
  </Step>

  <Step title="Read the feedback">
    An accepted code shows a green confirmation with the code name (for example, "SUMMER10 applied") and the discount appears as a **Discount** line in the totals. A code that doesn't fit shows an amber or red note (see the related troubleshooting article). Customers can add another code the same way, or **Remove** one.
  </Step>

  <Step title="Pay">
    The total updates with the savings applied. When the customer pays, the discount is confirmed on the order and its usage is recorded.
  </Step>
</Steps>

Because only one discount applies per line, entering a second code only helps if it matches a *different* item in the cart. A family can't stack two codes on the same program or membership.
