Kogan

In a move that will delight web designers and developers everywhere, Australian electronics retailer Kogan has announced that customers using Internet Explorer 7 (IE7) to make purchases will pay a 6.8 percent "IE7 tax." IE7 is the bane of online designers, as it's the least standards-compliant of the current pack. This means that designers need to do separate testing and design changes to make sites appear correctly in all browsers. According to Kogan, that's a quantifiable hard cost that it's no longer willing to pay.
