I've got a couple of questions on customizing the shipping options. If I have the following categories:
A: ship with live rates, handling fee flat $5 per order in this category
B: ship with flat fee of $10, handling fee flat $8 per order in this category
C: ship with flat fee of 15, handling fee of $3 per order in this category
If i'm reading the docs correctly, that means if I place an order products from all three categories, the shipping will be the live rate + $10 for cat B + $15 for cat C and a handling fee of $16 (total of all three) - is that right?
Is there any way to overwrite this so that we can use the most expensive of the 3 options rather than a combined rate?
