Any valid credit card, debit card, or PayPal-linked checking account can be used for purchases. You do not need a PayPal account in order to purchase items, as long as a credit or debit card is used. You also can use PayPal’s Express Checkout feature to pay from your PayPal account.
Returns are considered on an individual basis, but I do what I can within reason to keep customers happy. If you have any special concerns in that regard, please contact me.
