Website introduces Internet Explorer 7 tax
The site will charge a 6.8% tax on purchases for people using the browser - 0.1% for every month it has been around - on the premise it is making the internet a better place.
Chief executive Ruslan Kogan says his IT team have to put in extra effort to make sure the site appears correctly in Internet Explorer 7 format.
The tax pop-up suggests the user has been in a coma for the last five years and recommends several other browsers in place of the outdated Microsoft application.
