I want to modify ShippingWeight plug-in to set some rates following some rules:
- if the buyer and warehouse have same province, it has no rates;
- if the buyer and warehouse have neighboring province, it has some clear rates; - otherwise it has another rate.
How to modify that plugin to do that?
Do i need a separate domain for province and neighbor province in that plugin? If so, how can i modify nopcommerce plugin to add another domain?
