[ic] Shopping cart: basket processing

[Mark Weaver]

Hi all,

I'm somewhat in a quandry here with Interchange and how its processing 
the shipping charges of the shopping cart. I'm wondering if someone 
could tell me what file(s) are being used to process the shopping cart 
and calculate shipping.

What I'd like to do is modify the necessary files to do some custom 
shipping calculations, but I can't seem to find the program source code 
that handles these processes.

Thanks,
