Can you suggest an acceptable workaround until the issue is fixed? This client is just about ready to launch their new site. But not having a multi-box shipping option will essentially render the plugin and therefore the entire cart worthless. All their shipments will need to be multi-box for any order of more than one of their products.
The only solution I can possibly think of while we wait for the fix, is to put a notice on site that each basket must be shipped and therefore ordered individually. Any other ideas?
