This page contains very limited quantity and one of kind items for sale. I will attempt to remove items as fast as they are sold. If you should purchase an item that has already been sold, your money will be refunded as soon as possible. If there is an alternate item that you would wish instead, if the original item you selected has been sold, say so in the notes section on PayPal and I will contact you to resolve any price differential.
  • All items are priced with shipping. Persons buying multiple items maybe over paying. In each case I will compute the Paypal fee, packaging costs and postage and refund the excess promptly
