Base Rate + Extra Item Charge shipping means that the website visitor is presented with a choice of several shipping methods and their associated prices.
This choice becomes their 'base shipping charge' and will be the rate they are charged for shipping on their order as long as no more than X items are in their shopping cart.
If more than X items are in their shopping cart, then a charge of Y per item is applied in addition to the base shipping rate charge.
Make sure that you are running v4.9 or later.
This add-on will not function properly on any version earilier than v4.9.
How to find out what version you're running
Log-in to manage your website with Pro Edition (i.e. http://example.com/sohoadmin)
and look in the bottom right corner of the admin tool window (ie. in the footer).
How to update your version
If you're running v4.8.x or earlier than you've got to first update to v4.9 via Fantastico.
Once you're on v4.9 you can update to the latest build using v4.9's built-in Software Updates feature (Main Menu > Webmaster > Software Updates).
I just started using this plugin but it seems to have installed correctly and to be working just like I wanted. Kind of pricey but I needed it to be able to match the shipping I have on my auction items from a different site.
