By Walt Hickey A little advance warning, Numlock is off Thursday and Friday in observation of Black Friday and Black Friday Eve. StubHub eBay sold StubHub for $4.05 billion, and if there is any justice in this world they really got soaked on the service fee, the convenience fee and the fulfillment fee. The buyer was Viagogo, a slightly smaller company that also resells tickets but does so predominantly outside the United States, in Europe and the U.K. This move combines the two largest secondary markets for tickets, and I’m sure the average consumer will in no way be harmed by this horizontal market consolidation. eBay has owned StubHub since 2007, and the ticket reseller accounted for 14 percent of the company’s $2.6 billion in revenue in the third quarter.
