By placing a check mark in this field the system will calculate discounts (Mix & Match,
Multibuy and Disc. Offer) when Total is pressed on the POS, but not as each instance of a discount is detected.
This option is especially useful where items are included in many offers at the same time.
Calculating at the end can save time and by applying this feature you can avoid misunderstanding that
may arise if the offers that appear on the customer display screen are different from what eventually
appears on the slip.
