Our catalog boasts shipping by quantity... in other words, something like this:
Quantity 1-99: UPS Ground (Home) 24.95, UPS Ground (Business) 23.95, UPS 2nd day air 29.95, UPS Next Day Air 49.95
Quantity 100-199 UPS Ground 24.95
.... etc... which is calculated from the total number of items in the order.
Is there a way to set this up with custom shipping?
