EBay
eBay is an online auction site frequented by Chris. Chris has often puchased, and incidentally sold, stuff on eBay.
Chris as a buyer
Chris has been known for buying a lot of My Little Ponies from the site. His many eBay-purchases have helped Chris accumulate a debt of two thousand dollars on his credit-card. During the Megan Saga, Megan often got Chris to get her stuff, especially pics of Wehrmacht-soldiers, animé-cd's and Sailor Moon figurines, from eBay, probably because she didn't have a credit-card herself. It isn't entirely clear how these transactions went. She probably didn't pay Chris back after she recieved the goods.
Chris as a seller
Since the ending of 2008, when the Chris-Chan trolling became more known, people have been using Chris-Chan's eBay account as a means to troll him. They would bid on his auction, not pay, and then leave lulzy negative feedback. Early 2009, Chris tried to stop this form of trolling by changing his eBay-name, and deleting information from his account. It hasn't worked.
