Abstract
Described is a system and method for monitoring the expiration date of items and determining if an item previously picked by a user will expire before the next anticipated arrival date of the user at a materials handling facility. If the previously picked item will expire before the next anticipated arrival date of the user, the user may receive a recommendation to pick a replacement item so they do not have to return to the materials handling facility early to replace the expired item.
Claims13
A system for providing a reminder to a user relating to an item, comprising:
- determining, over a period of time and based on position data received from a portable device associated with a user, an arrival frequency of the user indicating a frequency with which the user visits a materials handling facility;
- determining, prior to an arrival of the user at the materials handling facility and based at least in part on the arrival frequency, a first date corresponding to a first anticipated arrival of the user at the materials handling facility;
- determining, prior to the arrival of the user at a materials handling facility and based at least in part on the arrival frequency, a second date corresponding to a second anticipated arrival of the user at the materials handling facility;
- computing a first difference between an item expiration date associated with an item previously picked by the user and the first date;
- computing a second difference between the item expiration date and the second date;
- determining, based at least in part on the first difference and the second difference, that the item will expire after the first date and before the second date;
- and
- in response to determining that the item will expire after the first date and before the second date, transmitting a reminder to the user, the reminder recommending that the user pick a replacement item from the materials handling facility during a visit by the user that corresponds to the first anticipated arrival at the materials handling facility.

A computing system, comprising:
- one or more processors;
- and
- a memory coupled to the one or more processors and storing program instructions that when executed cause the one or more processors to at least:
- determine, over a period of time and based on position data received from a portable device associated with a user, an arrival frequency of the user indicating a frequency with which the user visits a materials handling facility;
- determine, prior to an arrival of the user at the materials handling facility, an item expiration date for an item previously picked by a user during a prior visit to the materials handling facility and from an inventory location within the materials handling facility;
- determine, prior to the arrival of the user and based at least in part on the arrival frequency, a date corresponding to an anticipated arrival of the user at the materials handling facility;
- compute a difference between the item expiration date and the date to determine that the item will expire before the date;
- and
- based at least in part on the difference, send for presentation to a user, a reminder that the user pick a replacement item from the materials handling facility during a visit by the user to the materials handling facility, wherein the visit is prior to the anticipated arrival.
