Automatically merging pickup and delivery time slots from nearby stores

1. A system comprising:

one or more processors; and

one or more non-transitory computer-readable media storing computing instructions that, when executed on the one or more processors, cause the one or more processors to perform operations comprising:

determining a primary store and one or more secondary stores for pickup of an order of a user, based at least in part on a pickup type of the order, further comprising:

performing a first lookup call to a first cache of one or more proximate access points based on the primary store;

when a list of the one or more proximate access points is retrieved in the first lookup call, returning the list of the one or more proximate access points to determine the one or more secondary stores; and

when the list of the one or more proximate access points is not retrieved in the first lookup call:

performing a second lookup call to a second cache of active access points, locations of the active access points, start times of the active access points, and end times of the active access points;

determining the one or more proximate access points from among the active access points based on (i) absolute distances between a location of the primary store and the locations of the active access points, and (ii) the start times of the active access points and the end times of the active access points satisfying time window criteria, wherein cache entries in the second cache are invalidated periodically to freshen the second cache; and

storing the one or more proximate access points in the first cache to update the first cache;

determining real-time availabilities of first time slots at the primary store and real-time availabilities of second time slots at the one or more secondary stores;

generating a list of available time slots comprising at least a portion of the first time slots at the primary store and at least a portion of the second time slots at the one or more secondary stores, based at least in part on the real-time availabilities of the first time slots at the primary store and the real-time availabilities of the second time slots at the one or more secondary stores; and

facilitating displaying to the user a user interface comprising at least a portion of the list of available time slots.

2. The system of claim 1 , wherein the operations further comprise:

receiving a selection of a time slot from the user, wherein the time slot is one of the second time slots at the one or more secondary stores;

determining whether all items in the order are available at a secondary store of the one or more secondary stores associated with the time slot;

facilitating displaying to the user one or more items that are not available at the secondary store; and

receiving, from the user, a completion indication for the order.

3. The system of claim 1 , wherein determining the primary store and the one or more secondary stores further comprises:

receiving, from the user, the pickup type for the order;

determining the primary store based at least in part on the pickup type for the order; and

determining the one or more secondary stores based at least in part on the pickup type for the order.

4. The system of claim 3 , wherein determining the primary store further comprises:

when the pickup type is user pickup, determining the primary store based at least in part on a store selection by the user; and

when the pickup type is delivery-service pickup, determining the primary store based at least in part on a closest store to an address of the user.

5. The system of claim 4 , wherein determining the one or more secondary stores further comprises:

when the pickup type is user pickup, determining the one or more secondary stores based at least in part on one or more closest stores to the primary store; and

when the pickup type is delivery-service pickup, determining the one or more secondary stores based at least in part on the address of the user falling within respective delivery regions of the one or more secondary stores.

6. The system of claim 5 , wherein the one or more closest stores to the primary store are cached each day.

7. The system of claim 3 , wherein determining the one or more secondary stores further comprises:

determining the one or more secondary stores based at least in part on a store type of the primary store.

8. The system of claim 1 , wherein, when the pickup type is user pickup, the user interface further comprises (1) a description of the primary store, (2) a notification that the list of available time slots includes time slots from nearby stores, and (3) a description of each of the one or more secondary stores associated with the at least the portion of the second time slots.

9. The system of claim 1 , wherein generating the list of available time slots further comprises replacing unavailable time slots at the primary store during a predetermined time period with the at least the portion of the second time slots at the one or more secondary stores.

10. The system of claim 9 , wherein the predetermined time period is no more than two days.

11. A method being implemented via execution of computing instructions configured to run at one or more processors, the method comprising:

determining a primary store and one or more secondary stores for pickup of an order of a user, based at least in part on a pickup type of the order, further comprising:

performing a first lookup call to a first cache of one or more proximate access points based on the primary store;

when a list of the one or more proximate access points is retrieved in the first lookup call, returning the list of the one or more proximate access points to determine the one or more secondary stores; and

when the list of the one or more proximate access points is not retrieved in the first lookup call;

performing a second lookup call to a second cache of active access points, locations of the active access points, start times of the active access points, and end times of the active access points;

determining the one or more proximate access points from among the active access points based on (i) absolute distances between a location of the primary store and the locations of the active access points, and (ii) the start times of the active access points and the end times of the active access points satisfying time window criteria, wherein cache entries in the second cache are invalidated periodically to freshen the second cache; and

storing the one or more proximate access points in the first cache to update the first cache;

determining real-time availabilities of first time slots at the primary store and real-time availabilities of second time slots at the one or more secondary stores;

generating a list of available time slots comprising at least a portion of the first time slots at the primary store and at least a portion of the second time slots at the one or more secondary stores, based at least in part on the real-time availabilities of the first time slots at the primary store and the real-time availabilities of the second time slots at the one or more secondary stores; and

facilitating displaying to the user a user interface comprising at least a portion of the list of available time slots.

12. The method of claim 11 , further comprising:

receiving a selection of a time slot from the user, wherein the time slot is one of the second time slots at the one or more secondary stores;

determining whether all items in the order are available at a secondary store of the one or more secondary stores associated with the time slot;

facilitating displaying to the user one or more items that are not available at the secondary store; and

receiving, from the user, a completion indication for the order.

13. The method of claim 11 , wherein determining the primary store and the one or more secondary stores further comprises:

receiving, from the user, the pickup type for the order;

determining the primary store based at least in part on the pickup type for the order; and

determining the one or more secondary stores based at least in part on the pickup type for the order.

14. The method of claim 13 , wherein determining the primary store further comprises:

when the pickup type is user pickup, determining the primary store based at least in part on a store selection by the user; and

when the pickup type is delivery-service pickup, determining the primary store based at least in part on a closest store to an address of the user.

15. The method of claim 14 , wherein determining the one or more secondary stores further comprises:

when the pickup type is user pickup, determining the one or more secondary stores based at least in part on one or more closest stores to the primary store; and

when the pickup type is delivery-service pickup, determining the one or more secondary stores based at least in part on the address of the user falling within respective delivery regions of the one or more secondary stores.

16. The method of claim 15 , wherein the one or more closest stores to the primary store are cached each day.

17. The method of claim 13 , wherein determining the one or more secondary stores further comprises:

determining the one or more secondary stores based at least in part on a store type of the primary store.

18. The method of claim 11 , wherein, when the pickup type is user pickup, the user interface further comprises (1) a description of the primary store, (2) a notification that the list of available time slots includes time slots from nearby stores, and (3) a description of each of the one or more secondary stores associated with the at least the portion of the second time slots.

19. The method of claim 11 , wherein generating the list of available time slots further comprises replacing unavailable time slots at the primary store during a predetermined time period with the at least the portion of the second time slots at the one or more secondary stores.
