 Checkout 
 Once multi-inventory functionality is enabled, the following delivery scenario should apply: 
 
 When ordered product is assigned to a warehouse, the address of a warehouse is considered as a pick-up address for the shipping service provider.  Shipping rate to be calculated accordingly. 
 When ordered product is not assigned to a warehouse, the store address is considered as a pick-up address for the shipping service provider.  The shipping rate is to be calculated accordingly. 
 When ordered products are assigned to multiple warehouses, multiple orders are created.  Address of appropriate warehouse is considered as pick-up address for shipping service provider to each of the orders.  The shipping rate is to be calculated accordingly for each created order.

However, admin user should be able to create their own templates.  There it should be ability possible to specify email template that will be used for sending a notification (per warehouse or globally).
