Accept PayPal only.
I am a very prompt shipper, and charge very reasonable shipping fees, as well as packaging items well for a safe arrival. Sometimes I list items with Free Shipping available.
I do not accept refunds. I will be very specific in describing my items. I will state any flaws that I am aware of, and be glad to answer any questions before a purchase is made. I have been buying, and selling vintage toys for quite a few years.
