The transaction fees charged by Kickflip are always calculated based on the final discounted price before tax, only for Kickflip-powered items.
Here are a few examples to clarify:
If I purchase a Kickflip item priced at $100 before tax:
Transaction fees are calculated on $100.
If I purchase a Kickflip item at $150 before tax (no discount), and another Kickflip item at $200 with a 10% discount:
The transaction fees are calculated on $330 (i.e., $150 + $180).
If I purchase one regular (non-Kickflip) item at $500 before tax and one Kickflip item at $100 before tax, and apply a 10% discount to the entire cart:
The transaction fees are calculated on $90, which is the discounted price of the Kickflip item only.
IMPORTANT
Certain discount types are not supported by Kickflip. In these cases, it may be normal for the transaction fee to be calculated on the full product price rather than the discounted price. Refer to your ecommerce platform's documentation for more information on how to create a discount for your product:
