Hi, I am new to Bagisto.
I found that currently there are only 2 default shipping methods: Free Shipping and Flat Rate.
How can I implement custom shipping method to calculate shipping fee based on SKU weight, customer address postcode, and even customize free shipping criteria e.g. Buy 2 get free shipping / if total amount > X, get free shipping.
Since I'm going to purchase the Multi Vendor Marketplace extension, I am wondering if the shipping method can be set by the Sellers themselves?
