Refunds
Sellers are required to offer refunds for specific items when they are faulty or not as described. This applies to things like bespoke products, perishable goods, unsealed software or media (CDs, DVDs, etc.), and print publications such as magazines or newspapers. Refunds will be issued using your original payment method—if you paid by card, the funds will return to that card, while PayPal or bank payments will be reimbursed to your PayPal account. If you paid using a mix of methods, each part will be refunded accordingly. Sellers generally initiate refunds within three working days, though PayPal may take up to 30 days to complete processing.
