Hi Franz,

thank you for pointing me into the right directions!

Yes, I was surprised, too... :-)

Great!

And I added some more stuff:

I made the changes you proposed, but the configuration differs a bit.

OK, here we go.

I changed the "weight"-configuration as you did it ("type = weight"), it 
can now be configured differently for each entry in the 
"shipping"-configuration.

Now, this is how to define a minimum shipping cost depending on the 
category (PID of the page), a product has:

     10.priceTax.WherePIDMinPrice.155 = 7.5

Where 155 is the PID and 7.5 is the minimum price taken for shipping 
costs when at least one product in the basket comes from the page with 
that PID.

Example:

plugin.tt_products.shipping {
     10.title = Parcel
     10.priceTax.type = weight
     10.priceTax.WherePIDMinPrice.155 = 7.5
     10.priceTax.1 = 1.5
     10.priceTax.500 = 2.5
     10.priceTax.1000 =3.5
}

These are the changes in the tt_products - class:

I need tcemain for getPID, so this class has to be included.

Here comes the modified function GetPaymentShippingData, and the new 
function getPIDListFromBasket.
