Price:
For each reference in the order, Adoria looks to see if an equivalent reference is cheaper, all suppliers included, based on its unit price (without taking packaging into account).
Quantity:
For each reference in the order, Adoria looks to see if an equivalent reference is cheaper, all suppliers combined, based on the quantity ordered (taking packaging into account to get as close as possible to the number of units ordered, even if the unit price is cheaper).
Supplier:
For each reference in the order, Adoria checks whether an equivalent reference from the same supplier is less expensive.
