Promotions represent groups of services, products and courses with a discounted price.
Promotions are defined on a location basis.
A promotion that contains one or more products out of stock cannot be added to the receipt list.
Products out of stock will be listed in red colour.
A promotion item price discount is not cumulative with other receipt discounts (customer and manual discount).
Promotions in the receipt list are listed in blue colour followed by promotion title with the calculated discounted price value listed in red. If an item from a promotion is removed then all other items from that promotion will be removed and added again as normal items.
