VPCART will calculate the shipping price automatically by reading the shipmethods table. You need to update this table to reflect your shipping methods and costs.
The following table shows an example of how you could set up quantity shipping.
Shipping Method |
Base Price |
Extra Cost |
Express |
0 |

Base Cost is the amount that will be charged regardless of quantity.
Extra Cost is multiplied by the quantity of items ordered.
The total is the sum of the above amounts.
If you have specified that there are free shipping products and only those are purchased, then the shipping cost will be zero.
