In the price matrix it's not possible to select between all the units from the list of Product Units created in Settings > Ecommerce > Product catalog > Product units. Tested on DW9.8.8 and DW9.12.9.
The intension is to have 2 different prices on the product in the price matrix, one price for 1 item (piece) and another price if you take 6 items (box).
Am I misisng something here?
