## What you need to know

### Where should the field go?

Place the coupon field where it can be found without dominating the checkout layout. A collapsed or secondary field that expands when clicked keeps the path clear for shoppers who are paying at full price.

### What happens with an invalid code?

Show a clear message beside the field explaining why the code did not apply. Do not clear the entire checkout form or move the shopper away from their current step.

### How do promotions combine?

Define clearly whether multiple codes or automatic discounts can stack. A checkout that silently ignores a second code causes confusion; show what was applied and what was not.

### A quick store check

Test a valid code, an expired code and a combination of two codes. Confirm the message and discount are accurate without disrupting the rest of the checkout.

## Frequently asked questions

### Will hiding a coupon field help?

A visible but low-prominence field is better than hiding it entirely. Shoppers with a valid code expect to find it; if they cannot, they may abandon or contact support.

### Where do I configure discount and coupon settings?

Use current [discount documentation](https://help.getzenbasket.com/discounts/) and test code entry and error messages before publishing.
