Final answer:
The standard procedure for an overdue BOPiS order is to return the unpaid for items to inventory, allowing them to be resold to other customers.
Step-by-step explanation:
When a BOPiS (Buy Online, Pick-up in Store) order is overdue and has not been picked up by the end of the day, the standard procedure can vary based on the retailer's policy. However, the most common practice is to return the items to inventory, which is option D. Return them to inventory.
This ensures that the products can be sold to other customers. Discarding the items or donating them to charity is typically not the first course of action due to the potential loss of revenue. Reallocating them for resale essentially means returning them to inventory but may not necessarily be the same process.
