My client offers two shipping methods - standard and express. Express is only available on some products. The customer should be able to pick the shipping method for those items where they have a choice. I tried using different warehouses but that generates two shipments based on the product's warehouse, not just the products that the customer chooses express shipping for. (This was the solution described in this post: viewtopic.php?f=42&t=9869&p=42815&hilit ... uct#p42815)
Can anyone suggest other ways to do this? Perhaps with a product option or product upcharge for those items that are available via express shipping? If I did that, is there some way to group the items together by the selected shipping method, say one shipment for the standard items and one for the express shipment items?
