how to set up additional shipping each additional item

[rflores2323]

I have a flat shipping rate and want to add an additional amount for each additional item a customer chooses.  How can I do that?

so if a customer picks one item (flat rate) and then 3 additional items (a,b,c) 

flat rate (7.00) + A (3.00) +B (3.00) + C (3.00) = 16.00 total shipping costs

Also how do I set if an order totals a total amount that they would get free shipping?

joomla 1.5 and VM2

Shipping rate then must be set at weights -

Cost reduces the more you buy - so create the same shipping method but keep changing the weights.

In the end The software will only give you one shipping cost at a gradually reducing price.


* in Shipping you will have post 1, post 2, post 3 Post 4 and so on. all the same but low weight and high weight change. I've done this in many shops.
