Why can't I save product selection in Buy X Get Y discount option?

Topic summary

Issue: When creating a Shopify “Buy X Get Y” discount, the OP can check product boxes but cannot find a way to save/add the selection, so chosen items don’t appear in the discount after closing the window.

Current findings: Another participant tested the flow and sees an “Add” button after selecting items, and requested a screenshot from the OP to diagnose the mismatch.

Troubleshooting steps suggested:

  • Ensure the “Add” button isn’t hidden by a minimized viewport; scroll down or expand the window.
  • Clear browser cache and cookies to reload page elements.
  • If using Shopify’s mobile app, tap “Done” in the top-right after selecting products.

Context: “Buy X Get Y” is a discount type where specific products must be selected and confirmed (via an “Add”/“Done” action) to apply.

Attachments: A screenshot was shared showing where the “Add” button should appear, which is central to understanding the expected UI.

Status: Unresolved; awaiting the OP’s screenshot or confirmation after trying the UI/viewport and cache fixes.

Thanks for sharing your question with our network, @prairiefiberart !

In addition to helpful comments shared by fellow user, @yashgarg , I’d like to add that perhaps the reason you are unable to see the “Add” button is that your screen might be minimized or hiding it. Simply scrolling further down or expanding the window might help you see the option. If the issue continues to persists regardless, then make sure to clear your cache and cookies and try again to make sure all the page elements are loading.

If you are using the mobile app to add the discount, then you can select “done” in the top right-hand corner after selecting the products. That should work, but please let us know if you have further questions.

Warm regards,
