Two of the same product in one order, but from two different warehouses

[NielsTy]

Hi there.

 

Can someone guide me in the right direction here:

 

I have two warehouses; one is my actual store, another is a warehouse for the manufacturer.

Now, shipping from the store is free of charge and takes 2 weeks. Shipping (directly) from manufacturer costs money and takes 6 weeks.
(i have created a carrier for each warehouse)

 

Obviously, i would like to offer those products in the store first before start selling from the manufacturer.

Here is the problem... i have ONE of a specific product left in my store, and the manufacturer has a billion of them.

If a costumer wants to buy TWO if this product, how can i configure PS to take the one in my store AND one from manufacturer, and ONLY show the carrier that is setup for the manufacturer... meaning, costumer has to pay for delivery.

 

As it is for me now, in the basket can be chosen both the free delivery and the payable one...!

 

Cheers!
