hi ,

here my question is: i am using zone rates for shipping.even specifically i want a shipping cost should calculate as below.

i am having 2 categories of products.
i am adopting 50cad to ship to canada and 60cad to USA. i want this should calculate accordingly by categories. for first category i want to put 40cad and for second category 50 cad if it is canada and if it is USA it will differ for both categories. if users buy both categories then it should take the maximum.

can any one help me? atleast now i need "category based" shipping rather "calculating zone with category based" shipping.

Thanks in advance.....
