  • Discount requirements (eligible products, codes) might not be met at checkout

Suggested solution:

Hi, @ccelia

Thanks for posting. I hope your day is going well!

It sounds like you have a discount option built into your theme, or you have a discount app installed, but the code or discount is not translating to the checkout. In order for a discount to work, the requirements need to be met at the checkout. This means all applicable products are added, and if a code is required, it is entered at the checkout.

Can you provide the discount requirements as well as your domain so that I can test this for you?

Was your ‘buy x, get y’ discount an automatic discount? If so, we had the same issue with our website and found out that it was because the checkout button was coded as a rather than an . Switching our checkout to solved the problem for us.
