Extra
Besides the website, Jason had two other activities later on. First was changing his last name for one year by setting up a BuyMyLastName.com, and putting his name on the auction for various companies. The biggest bidder was Headsets.com ($45,500), so he quickly became Jason Headsetsdotcom. Now, he is Jason Zook. He took that name from his grandfather.
Another extra is Jason's book about his IWearShirt adventure. The book contains the case study of IWYS, such as the revenue, marketing strategies, and so on. He set up SponsorMyBook.com and finally got a total of $75,000 from sponsorships. At the time of writing this, his book is between $12 and $25 for a single copy.
