If you’re one of the 6 folks out there that hasn’t yet taken the plunge on an XBox 360, you might want to wait a week or two before heading to your local retailer. A recently leaked K-Mart ad scheduled to run on the 6th of July depicts an XBox 360 premium being advertised for the low price of $299. This represents a price drop of $50, making it quite the bargain for anyone in the market. As a refresher, the Premium system includes a 20 GB hard drive, a single wireless controller, a wired headset, and component cable. There’s no confirmation from Microsoft, but given the upcoming E3 convention, we’re not at all surprised to see Microsoft making play for more customers.
