Plugins - Postman
Add to favoritesThis plugin is calculates the shipping rate for a given location and weight. It is useful for cases where the postal service in your country doesn't provide APIs for calculating shipping rates.
What Postman does is to get the values from the tables and calculate it out. The values are found in your database tables. You'd have to add the mailing rates into the tables for it to work.
The plugin is very simple. I've included some sql files to help put in the countries and mailing rates(in Singapore). You can use them as a reference.
And here's the original rates:
