I've a store setup on Magento 2.2.3
I use two payment methods: COD, Credit Card Payment
There are 2 allowed countries (for example A and B)
Country:A shipping is flat (i.e. 10 USD)
Country:B shipping is calculated according to weight table
What I want: For
Country:A when user selects
COD as payment method, additional shipping charges (5 USD) should be charged (i.e. 10 USD + 5 USD = 15 USD)
How do I achieve this in Magento 2.2.3 so that I could set additional shipping charges from admin and User is shown additional charges at front?
Kindly tell me if there's any free existing module/extension available for this.
