Show shipping class for selected products and charge per item

[adaptive]

Hi,

I am trying to setup a shipping rule where only selected products can be shipped with a certain class e.g. Next day.
Normally, one would use a weight based calculation where the products not available for shipping in the class are given a false weight that is beyond the weights range.
However, I wish to apply a fixed per item charge for the shipping class as well, which could be done using categories.
Additionally, where a combination occurs, the class cannot be applied.

For example:
Product A can be shipped next day and must be charged at £3.00 per item
Product B cannot be shipped next day

If customer buys 2x Product A they can ship by Standard delivery or Next day delivery. Next Day delivery will cost an extra £6.00 (2x£3.00).
If customer buys 2x Product B they can only ship Standard delivery.
If customer buys Product A and Product B they can only ship Standard delivery.


I'm truly stuck, so any suggestions will be greatfully received.

Jon Whitby.

Can you show us what you have setup so far as it will be easier to correct that than create it from scratch. I can't see why shipping by weight will not work, perhaps you could show us the weight setup that failed.
