Why doesn’t the discount code box appear in the checkout?

Our price add-ons use draft orders which aren’t compatible with the discount code box on the checkout page.

In order to solve this problem, the app provides the function of discount input box on the shopping cart page. Please open the settings below

The app also provides 2 other principles to achieve price addition, these 2 principles can solve this problem

Binding variant principle:

Bind option A to variant A. After option A is selected, the bound variant A will also be added to the shopping cart. Please refer to the attached iamge 1

The one-cent principle:

Create a one-cent variant in shopify. If the add-on price is $100, 10,000 one-cent products will be added at checkout, which is exactly $100.

This principle is not open yet, if you need it, please create a one-cent variant in the shopify background, and send me the variant id, and I will set it up for you.
