Change total amount in the shopping cart

[blaupunkt]

I am doing some tests and I was wondering how can I manipulate the total amount in the shopping cart. Where are the calculations done when a customer adds more than 1 item in his basket?

The calculations are made within the so called order_total module.
There is a module and a class for this.
Scan your files for this term and you'll find what you are looking for.
