After your product is donated or returned, feel free to call us to expedite your refund. We will credit the card you used at the time of your purchase or process your refund via Affirm.com. Credit card refunds can take 3 to 4 business days to show up in your account depending on your banking institution. PayPal refunds are immediately transferred into your account. In some situations, we may need to issue refunds via paper check through U.S. mail, but this is typically due to a change in account information or delayed processing.
