With the seasonal savings and madness of Black Friday (a.k.a. the day after Thanksgiving) fast approaching, retailer Walmart seems to be getting a head start on the craziness. As part of the "one day in-store specials" that kick off at 8AM this Saturday, November 7, the chain will be rewarding those that purchase the $199.99 Xbox 360 Arcade console with $100 worth of in-store credit via gift card.
The sale only runs one day, with the fine print at the bottom of the advertisment cautioning: "Quantities are limited. No rainchecks. Prices and availability may vary in AK, HI, OK and WI. Not valid in Puerto Rico or on Walmart.com." Kotaku reports that more notable sales are due in the coming weeks, though its sources offered no specifics.
The Arcade model is the cheaper of the two Xbox 360 models on the market. Unlike the $299 Xbox 360 Elite, the Arcade does not include a 120GB hard drive. Instead, it packs 512MB of on-board memory for game saves and downloaded content. Xbox 360-branded hard drives are, of course, sold separately should more space be needed.
