Priced out of the most expensive real estate market on earth? Get an acre of lunar property for US$24.99

Several websites in the United States are selling title deeds that purportedly grant the buyer ownership to frontier land on the moon.
For US$24.99 , Lunar Embassy in California sells a piece of parchment that proclaims the customer the owner of an acre (43,560 square feet) of lunar real estate. On the 50th anniversary of the Apollo 11's moon landing, the website is selling plots 10 miles from the landing site.
