Why only buy shoes when you can shop for some clothes to go along with them? As reported by TechCrunch, Amazon.com's acquisition of Zappos.com last month also brought the Clothes.com domain to the online-retailing giant.

The $4.9 million Zappos.com paid for the Clothes.com domain would have been 2008's second-largest reported domain-name transaction, following Fund.com, which went for $10 million, and it would have come in No. 2 for 2009 so far, as well, behind Toys.com, which carried a $5.1 million price tag, according to TechCrunch.

From Amazon.com's Securities and Exchange Commission filing, with the "we" referring to Zappos.com:

In May 2008, we acquired the Clothes.com Internet domain name from Idealab. The domain name was recognized as a purchased intangible asset with a useful life of 20 years. The entire purchase price of $4.9 million was assigned to the price of the domain-name intangible asset and will be amortized on a straight-line basis over its remaining estimated useful life.
