If Amazon grants you the returnless refund, you'll get to keep the item you purchased and retrieve your money.
How does a Returnless refund work on Amazon?
Under the new policy, sellers will not be able to offer assistance to customers before their items are returned. The "returnless refunds" feature enables sellers to offer a refund on certain products that are expensive to ship for customers to return or are difficult to resell.
How long does a Returnless refund take on Amazon?
Returnless refunds allow sellers to quickly resolve product issues such as defects or purchasing errors. In normal circumstances, refunds can take up to 3-5 business days and require customers to bring back the product in question. On Amazon, returnless refunds are an optional feature for Amazon third-party sellers.
