Sneaky Business learned today that the domain name pizza.com has been bought for a whopping $2.6m. That's almost $0.5m per slice. Given that the domain owner, Chris Clark from Maryland, had maintained the site for a mere $20 a year since 1994, this represents an astonishing return on his investment.

According to the BBC article on pizza.com, Mr. Clark was prompted to sell after learning of another sky high valuation for a similar site, Vodka.com – that sold for $3m in 2006. "I thought, 'Why don't I just try to see what the level of interest is?'" Mr. Clark said. "If someone's willing to pay that much for Vodka.com, maybe there's more interest in pizza.com."

Interestingly, the pizza.com price-tag wouldn't even make the top three list of time most expensive list domain name sales. That list is dominated by two adult oriented sites – though, intriguingly, seniors.com was also picked up for $1.5m. And Tandberg managed to shell out $1.5m for the rights to use their name on their website. We're sure they must be very pleased about that investment.
