For each shipping zone you will need to enter a maximum value. The shipping amount that you will need to enter is the word “max” and the shipping charge for this amount will be whatever you want to charge for shipping. An example would be:
10 1
Max 2
This will charge $1 shipping between 0 and 10 and $2 for anything over 10. This applies to the following shipping models:
Price Threshold
Weight Threshold
Quantity Threshold
