Implementation principle of app option price add-on

1. Draft order (default)

2. 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

3. 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.
