Hack an ecommerce 'site with only your browser, somehow news at ZDNet:

Here's how it works: After choosing a product and receiving pricing information, a hacker can use a standard browser's "edit page" feature to show the hidden HTML code on the page. The thief then saves the page to his computer, alters the price information and then hits the "publish" key on the browser. In many cases, that page is then accepted by the shopping cart software - and that $999 watch becomes a $3 special.

Hacker? Hidden? Thief? Alters price information? Price information? In the url? Like "cost=5"? The only valuable information this article gives me is the exact percentage of kill-them-now-for-their-own-good stupid people running dot coms. [via MeFi thread.]
