gogreen Expo
Here is the show schedule:
Los Angeles — January 22 – 24, 2010 • LA Convention Center
New York City — March 19 -21, 2010 • Pier 92 (co-located with Architectural Digest’s Home & Design Show)
Philadelphia — April 16 – 18, 2010 • Greater Philadelphia Expo Center at Oaks

Normal show price is $10; business owners will be able to visit the show a day before official opening for free. They will be issued passes that can be used for the remainder of the show, in addition to the first day.
gogreen Expo is a lot of fun, and definitely worth checking out. I went last year and got free fluorescent light bulbs, tote bags and product samples. A business card got me in free on the day before official opening, and the whole fair was operational.
