Free in NYC
NYCgo.com's weekly list of free activities, exhibitions and shows.
Besides this list of free classes - which range from free yoga classes to crafty gatherings to tax and financial assistance - this website lists free walking tours, museum dates and city bargains.
Craig's List listing of free stuff. New Yorkers are always giving up stuff as our space is so limited. I've scored some cool stuff from Craig's, including a free toaster oven.
The city's free sexual and mental heath clinic. Even the drugs are free, and everyone can use it, no questions asked. Get there early and the line isn't so bad; there's no excuse for not being tested for STIs! NYU also offers a free health clinic that is more all-encompassing, but patients have to qualify for the free health insurance first (http://www.med.nyu.edu/nycfreeclinic/).
New York magazine's list of free stuff, discounts and bargains to be found around the city.
