Additional item :$2

Answer 1

You need to create a new shipping computation plugin.

The easiest way is to copy from another plugin such as Shipping.FixedRateShipping and change the name.

Then modify the method GetFixedRate to return the rate depending on the number of quantities, etc..

Follow these steps to install and configure your plugin: http://www.nopcommerce.com/docs/77/how-to-write-a-nopcommerce-plugin.aspx

I hope this helps.
