The tax amounts to 6.8 percent. Naturally, you won't see any tax notification unless you are using IE7. Heaven forbid you use IE6.
The screenshot above shows exactly that you'll see. It says:
"It appears you or your system administrator has been in a coma for over 5 years and you are still using IE7. To help make the Internet a better place, you will be charged a 6.8% tax on your purchase from Kogan.com.
6.8 percent is a decent chunk of change. We'd expect that most people would be far more willing to upgrade their browser than pay it. On the other hand, it makes for good publicity for the site.
Back in 2008, Kogan said it would ship the second Android phone - EVER. That phone never shipped.
