Wondering if anyone might have a solution for the following scenario;
I have a customer that would like to buy 3 rolls of printing paper. He would like to send one roll Overnight shipping and the other two rolls sent Standard Ground shipping. How can I allow customers ordering online to have this flexibility in their shipping of orders?
Not possible to accomplish what you are exactly trying to do.
You can provide approximate rates at checkout by offering shipping rates for all products using Shopify flat-rate shipping or carrier-calculated shipping rates
