What if I do a return or exchange on a purchase made through installments with PayPal?
If your return is approved, the refund will be sent back to your original PayPal payment method. Processing time is typically 3–10 business days, depending on your bank or payment provider.
If your refund is less than your remaining balance, your installment schedule may be adjusted, which could result in fewer or smaller payments.
If your refund exceeds your remaining balance, the difference will be returned to your original payment method.
