If you're looking to pick up some worthwhile video games at a discount, then today is the day to watch Amazon.com's Lightning Deals as the online retailer is holding another of its frequent all-games-all-day events.  Zumba Fitness for the Microsoft Xbox 360 and Nintendo Wii is the Gold Box deal today, while the blink-and-you'll-miss-'em sales involve F.E.A.R. 3, Mortal Kombat, Grand Theft Auto IV: Complete Edition (which includes the two downloadable expansions), something for fans of Blizzard's strategy games, and much more.  As always, every purchase you make through the green link here goes to help support Press The Buttons which, also as always, is greatly appreciated.
