What's so special about 9/9/2009? Numerologists will tell you it's an auspicious date with powerful numbers, ancient cultures believe the number nine represents long-life (Chinese) or bad luck (Japanese), and more practically it's the last time we'll see a single digit, repeating date until January 1, 3001. Oh, and marketers from movie studios to hoteliers to wedding chapels are taking advantage of the good fortune of the date to launch films and offer discounts and deals.The number 9 also has significance for Center'd, since the 9 dots in the center of our logo help complete the 28 dots of this centered nonagonal number. At any rate, we figured we'd get in on the fun by highlighting some local businesses that are offering deals today or that have the auspicious number 9 in their name.Deals & discounts:Restaurant.com - Offering more money off its usual discounts: Save 90% off with every $25 Gift Certificate order.
