Microsoft seems to have figured out a game plan that works: Drop your prices, and more people will buy your product. After a price drop to $199 last week, the Xbox 360 has doubled in sales.

The company also happily pointed out that "retailers are reporting that between Friday, Sept. 5 and Sunday, Sept. 7, some Xbox 360 models were selling at six times the rate they were the weekend prior."

Not a terrible way to begin the push into the holiday season.
