(Off screen: Free Shipping: For shipments with matching items).

6. Enable the Free shipping delivery method:

Hello @kassner
cc: @engcom-Bravo

It seems not a bug but an expected result.
FPT it's not the same as regular tax in Magento.
The main use case for this attribute(FPT) its e.g. state/country law like "all plastic or electronic stuff must have an additional $$ for recycling /utilization"
So applying a discount on FPT could violate the law

[kassner]

@sdzhepa while I agree for some cases, this render some impossible order scenarios. Stripe, for example, requires a minimum of $0.50 in a payment, so when we try to charge $0.08 for the French WEEE tax, the customer is not able to place the order. My finance department asked me to, if the order is completely free disregarding the WEEE, do not charge it, as, technically, there isn't a sale being made.

I don't want to always apply discounts on top of the FPT, but it's important that this can be configured for the legitimate use cases.

Thank you for your feedback @kassner!

I got your point about improvement.
I will discuss it with Product Managers for the final decision(approve/reject).
