In the case of AliExpress's Local Return service, the buyer is responsible for the return shipping costs. This service gives you a 15-day window (on top of the on-time delivery date) to decide if you want to keep or return the item for any reason. If you opt to return the item, it will be shipped to a designated local return address, and you will bear the cost associated with this return shipment as the buyer. Therefore, always be sure to understand the return policies and potential costs before purchasing to avoid any unexpected expenses.
