Get help with installation, billing, shipping-rule configuration, or checkout testing. Include your store domain, the rule involved, and the delivery methods you expected to see so the issue can be reproduced quickly.
Quick start
- Create a rule and choose the condition you want Shopify to evaluate.
- Enter the checkout delivery method the rule should control. Use the name customers see at checkout.
- Save the rule, then run one checkout that matches and one that does not.
- Confirm the intended method changes and that at least one delivery method remains available in both tests.
Postal and delivery-method patterns support * as a wildcard. For example, M1M* matches postal codes beginning with M1M, while *Express* matches a method containing Express.
