Combining the free shipping code with a welcome offer (discount)

Topic summary

A merchant is experiencing an issue where free shipping codes don’t combine with welcome offers for first-time customers, even when orders meet the free shipping threshold. Other discount types combine successfully.

Suggested Solutions:

  • Check app settings: If using an app to generate welcome discount codes, verify that the “Combines with shipping discounts” option is enabled in the discount settings (see attached screenshot showing this checkbox)

  • Use Shopify Discount Functions: These allow combining order and shipping discounts through custom logic at checkout, though they require development work

  • Third-party app: Single Code Discount by Swiftbee enables creating one code that applies multiple discounts simultaneously (e.g., percentage off + free shipping)

The issue likely stems from how the welcome offer discount codes are configured rather than a platform limitation.

Hi All,

I have been able to combine my Free Shipping code with all product and order discounts. The only time that hasnt held true has been when the customer uses the welcome offer (first time customer). In this scenario the customer pays for shipping even though its over the threshold.

Has anyone else had this problem?

If yes, what has been the solution?

Are you using an app that’s automatically generating the welcome offer discount?

If yes, then see if the settings allow you to generates each discount code such that it combines with Shipping discounts. If you review any of your existing welcome discounts, you’ll probably see that this box isn’t checked.

Using Shopify’s Discount Functions order and free shipping together can be created, which offer more flexibility through custom logic at checkout but they require development work using sing discount code.

However, we built an app specifically to solve this problem:
