There is absolutely no store that I've been to that sells shuttles, other than the top of the line Yonex or Wilsons, which are all above 30$+. If I would want to buy, I'd have to buy from someone else, this is very bothersome.
I believe www.brooklynbadminton.com sells Aeroplane (black) for $21, which is a very good local deal, consider it's the top notch shuttle. If you prefer some lower end choices, www.nycbadminton.com sells various TL, Wilson, Yonex ones. If you would like to purchase from either one, try to contact them, and visit/purchase/pick up in person is the best method.
Thanks LazyBuddy, heard you're quite popular among the NYC players! I go to BBC often, Ball Gor is really nice, I might just get AERO(B) from him.
