How much do I hear for a hole in Excel?

That Excel vulnerability for sale on eBay was indeed pretty funny. eWeek's story on that explains,

The seller openly taunts the software giant, poking fun at the company's delays in providing fixes for known security bugs. "It can be assumed that no patch addressing this vulnerability will be available within the next few months. So, since I was unable to find any use for this by-product of Microsoft developers, it is now available for you at the low starting price of $0.01 (a fair value estimation for any Microsoft product)," the listing read.

"Microsoft representatives get 10 percent off the final price. To qualify, you MUST provide @microsoft.com e-mail address and MUST mention discount code LINUXRULZ during checkout," it added.
