Price Percent

This method calculates the shipping cost as a percentage of the total cost of the order. This is done by setting the xfixedshippingcost value to a percentage value.

To set up percentage price shipping, you need to set the following Software Configuration options:

xshippingcalc

PricePercent

Xfixedshippingcost

If you want the shipping cost to be 20% of the order cost, then set this to .20.

If you have specified that there are free shipping products and only those are purchased, then the shipping cost will be zero.
