Complex shipping?

[Insperio]

Hi,

I got quite an annoying problem with shipping rules in my shop.

I had it all set correctly but now I also decided to use drop-shipping from other company to boost my sales. Some of the product go from my place, others from other country. The shipping prices need to be different for both of them. 

 

Any idea how can I achieve this?

I tried quite a few things but I'm always stuck when it comes to situation when client purchase one item from me and one more from my drop-shipping partner. The shipping rules does not work then  I simply got information that there is no carrier available. However, if they purchase them separately (as two separate orders) the prices seems ok.

 

Any ideas?

 

Thanks
