How much would you pay for a pizza? Chances are not as much as the anonymous bidder who won the auction to relieve entrepreneur Chris Clark of the pizza.com domain. Clark invested in pizza.com in 1994 for just $20, and even allowing for his annual $20 domain registration fees he has turned a pretty healthy profit considering the domain went for a staggering $3 million. Funnily enough that's the same amount that vodka.com sold for in 2006.

According to the BBC news report Clark had hoped back in 1994 that buying pizza.com would help to get a contract with a pizza firm for his consulting company, something that didn't happen. When the business was sold in 2000, he kept hold of the domain and used it as a vehicle to sell advertising.

In perhaps the greatest bit of understatement of all time, the BBC says that Clark now regretted not buying more domain names in the 1990s.
