Australian electronic online retailer: Kogan
According to Mr Kogan the idea was born when the company started working on a site relaunch.
Mr Kogan said that even though only 3% of his customers used the old version of the browser, his IT team had become pre-occupied with making adaptations to make pages display properly on IE 7.
"I was constantly on the line to my web team. The amount of work and effort involved in making our website look normal on IE7 equalled the combined time of designing for Chrome, Safari and Firefox."
Mr Kogan said it was unlikely that anyone would actually pay the charges. His goal is to encourage users to download a more up-to-date version of Internet Explorer or a different browser.

I think it's pretty brave to increase cost of items for consumers unless they felt they had to. Most sites would just deal with it or find funding with other means instead of being public about it.
