Patent attributes
A facility for assessing product replenishment is described. The facility determines that a purchasing entity possesses an item, determines an expiration time for the item, and schedules, for a time preceding the expiration, a unilateral communication to the purchasing entity indicating that the item should be replenished. The facility can also manage automatic item replenishment, including determining a target date for replenishment of the item, transmitting to the purchaser in advance of the target date (when the purchaser is not engaged in an electronic shopping activity) a replenishment proposal, and ordering a replacement for the item. In some cases, the facility places an order within a predetermined tolerance of the target date without intervention by the consumer. The facility can also establish and test a condition for suggesting replenishment, can raise an event when the condition is satisfied, and can unilaterally make the replenishment suggestion when the event is raised.
