Transient class representing a discount that a
LineItemCtnr
"almost" qualifies for based on the amount of merchandise in it. Storefronts
can display information about approaching discounts to customers in order to
entice them to buy more merchandise.
Approaching discounts are calculated on the basis of a
DiscountPlan instead of a LineItemCtnr itself. When one
of
PromotionMgr.getDiscounts(LineItemCtnr) or
PromotionMgr.getDiscounts(LineItemCtnr, PromotionPlan) is
called, the promotions engine calculates the discounts the LineItemCtnr
receives based on the promotions in context, and also tries to determine the
discounts the LineItemCtnr would receive if additional merchandise were
added. DiscountPlan provides different methods to retrieve this approaching
discount info. Merchants can use these fine-grained methods to display
information about approaching order discounts on the cart page, and
approaching shipping discounts on the shipping method page during checkout,
for example.
The merchant may include or exclude individual promotions from being included
in this list, and define distance thresholds when configuring their
promotions.
