# Add a discount code box to the cart drawer

> Let shoppers type a discount code in the drawer instead of waiting for checkout.

Turn on the **Discount code** card in the cart editor. Shoppers get a code box with an **Apply** button in the cart footer. Codes they apply carry on to checkout.

## Set it up

1. In Shopify admin, open **Apps** → **Section Store** → **Cart Drawer**.
2. Click **Edit** on your cart.
3. Under **Footer**, find the **Discount code** card. If it isn't there, click **Add block** and pick **Discount code**.
4. Turn on the card's switch. A block you just added is already on.
5. Click the card to open it.
6. Set **Title**, **Placeholder** and **Button text**.
7. Set **Error message**. The default is "The coupon code is invalid."
8. Pick **Collapsed by default** or **Expanded by default**. **Make it collapsible** is ticked by default. Untick it to keep the box open.
9. Click **Save**.
10. Test a code on your storefront. You see "Discount applied." and a tag with the code.

## How it works

- A new code joins the codes already applied. Shopify decides which ones combine.
- Each code shows as a tag with an x to remove it.
- Order discounts from the reward bar show as tags like "- 10%". Shoppers can't remove those.
- When the cart empties, we clear the codes.

## What shoppers can see

- "Discount applied."
- "Discount removed."
- "Enter a discount code."
- Your **Error message**, for a code that doesn't work.
- "Discount applied, but some free gifts are now charged."

## If it doesn't work

- **A good code shows the error message:** Shopify refused it. Check that the code is active and that the cart meets its rules.
- **A code removes a reward:** the code doesn't combine with the cart's discount. See the article below.
