I think there is a typo somewhere.

Shipping and handling: US $500.00 (within United States)

Buyer pays for all shipping costs
Shipping insurance: Not offered

Will ship to United States only.

Seller's payment instructions:
Money Order or Cashiers check, or PayPal. Buyer pays $5.00 shipping.

Otherwise I am sure that Ebay would remove this auction as the seller is clearly trying to lower the auction fees...
