I would like to be able to create pricing rules based on the total order quantity of different item lines.
I think the use-case scenario is simple, and commonplace.
eg, Printing customised T-Shirts and other apparel. A wholesale order often consists of many line items in smaller quantities, both different products and product variants. The “print/design” is the same on each garment, so the size of the print run is determined by the combined total, rather than each individual line item.
I’d like to be able to create pricing rules based on this combined order total quantity.
