Step 1: Prevent Customers from Purchasing Return Coverage
In Shopify, go to the product and add a Tag or assign it to a Collection (e.g., "Non-returnable").
In Your Return Settings:
Navigate to Settings > Coverage > Return Coverage.
Under Exclude Collections, enter the Tag or select the Collection from the drop-down menu.
Save changes (top right of the screen).
The item will now automatically be excluded from return coverage at checkout.
Step 2: Reject the Item in the Return Flow
Go to Settings > Return Flow.
* We recommend adding this step towards the top of your return flow. If you don't feel confident with the return flow, try watching this video overview.
Select the step type, it should be "Condition", then select Condition: Customer tags or Collections.
Add the tag or collection you want to exclude and select "If matches, then" and create a new "Reject" step from the drop-down menu
This new step will reject any item with the Tag and will display a message to your customer when they are rejected.
Finally, go back to the Condition step and select, "If does not match, then" and "Use an existing step" from the drop-down menu.
You'll want to select the original step that connects to the rest of your return flow.
Then Save and Publish the change!
Now, the system will block returns for these items while keeping the rest of the return process functional.
