One box seller said his listing was just a joke.
"I never (actually) thought people would bid on this," wrote the seller, who goes by the eBay screen name "silentbarrel," in response to an e-mail inquiry Friday. "I thought most people that were spending any money on anything would read what they are buying."
"Silentbarrel" wasn't even offering a real Xbox box, but rather a homemade one. He explained that he had alerted the buyer to the ruse after the auction ended, saying not to send the $611 payment.
