How to setup 'Custom price'?
I want to implement the following behavior, but have had no luck so far.
If a customer has setting that tells the POS to use PriceA (a discounted price) instead of the Regular Price and
if an item has both a Regular Price and a PriceA, then, when that customer is selected, only show, and use, PriceA.
If other items, that the customer wants to purchase, do not have a PriceA, then the POS will use the item's Regular Price.
Is this doable?
