For merchandise returns, you will need to deal directly with the merchant; each merchant has its own return policy. Keep the card and purchase receipts, even after the balance is depleted, as you may be asked to present them in order to process the return. When the merchant’s policy is to credit the card used for purchases (rather than provide cash or a store credit), the available balance on the card will be increased by the amount of the refund (typically within 3 days).
