Q. What is the format of the Shipping Rates text area?
A. Syntax:

Max weight| Cost | country group number | Method title

One rate per line.

Example:

10|6.95|3
20|7.99|3
20|17.99|3|First class
0|1.11|3
100|27.33|0

The separator is a vertical bar ( | ) or a forward slash ( / ) or a comma ( , ).
Blank space is ignored.
For decimal values in the Cost, use a dot not a comma.
Use a non numeric value in the Cost field when the maximum weight has been exceeded.
Use country group number 0 if you want to set default rates for all other countries.
Use Max weight 0 if you want to support carts with zero weight.
Method title is optional.
Use the Method title to differentiate between multiple rates for a weight range.
