Affordable organic fruits and vegetables in NYC (east side?)
Here's the Greenmarket schedule. http://www.grownyc.org/ourmarkets Not sure how good the markets are around Murray Hill, but you're pretty close to Union Square and they have the best produce in the city. (although some of it is not certified organic)
Also, Fairway (UES and coming to Kips Bay) and Whole Foods (new one in the east 50s) can have good deals on organic produce. They're usually cheaper and have a better selection than mom and pop organic shops.
