I've added COD as a payment method.
The shipping rates for COD are very different (more expensive) than normal shipping rates.
So I have created a new geo zone for COD shipping rates and put these rates in weight based shipping. I have associated COD payment with this COD geo zone.
So now, in shipping, customers are able to select COD in shipping and COD in payment, and that's great.
Problem is, they can select normal shipping (cheaper) in shipping and COD in payment method. I don't want that. They shouldnt see COD in payment options unless they have selected COD in shipping.
Conversely, if someone selects COD in shipping, they shouldnt see any payment option except COD.
Please help
