So I created a bunch of products. Some come from supplier A and some from Supplier B. Supplier A has its own shipping rates and Supplier B has their own rates too.
I create a series of rates.
- Ground A
- assigned to Supplier A
- Ground B
- assigned to Supplier B
etc.
If I add an item from supplier A to my cart and check out, it gives shipping rates and lets me buy. If I add an item from Supplier A and from Supplier B it says, no shipping methods are available.
What is the conflict?
