First Item plus Additonal Per Zone per Category - How?

[jody00]

Basically I want to extend First Item flat cost plus additional items flat cost per zone to

 

First Item flat cost plus additional items flat cost per zone per category or sub-category

 

Each category has a first item plus additional item cost

 

C1(first)(zone), C1(additional)(zone)

C2(first), C2(additions)

 

If 1 from each category add the first costs – C1(first) + C2(first)

 

If 2 from a category C1(first) + C1(additional)

 

If 2 from C1, 3 from c2, 1 from c3 = C1(first) + C1(additional) + C2(first) + C2(additional) + C2(additional) + C3(first)

 

I sell things that don't go together shipping wise: One category is posters (in tubes cost one thing and each additional is very little extra shipping), one category apparel (in box cost one thing and each additional is very little extra shipping but different to posters), One category is boxed toys (in boxes each item additional is significant)

 

Extending the First Item flat rate cost per zone to be sub category specific should address this i would imagine and it shouldn't be that hard even if it has to be coded into the shipping module what the costs are per category and get the category id's in the module - i imagine the complex part is the working out on the shipping page which category the item is in although this could be added to check out process to pass that variable into the shipping module

 

any ideas?
