Final answer:
The store should refuse the return because the price tag is missing and the return was made after the specified time period. However, a store credit could be offered as a gesture of goodwill. Contacting customer service for further instructions is also an option.
Step-by-step explanation:
The store should refuse the return because the return policy clearly states that the price tag must still be attached to the item. Since the customer failed to return the item within the specified 10-day window and without the price tag, the store is not obligated to accept the return.
However, as a gesture of goodwill, the store may consider offering the customer a store credit. This would allow the customer to use the credit towards a future purchase at the store.
If the store is unsure about how to proceed, they can contact customer service for further instructions and guidance on how to handle the situation.
