answer:Pearl Paint, on Canal Street and Broadway. I went there all the time in highschool. Take the NQRW or 456 or JMZ (or 1, A, C, or E, but it’s a short walk) to Canal Street. It’s like art mecca. The prices can’t be beat and they give students 10% off. (I also have a tax free card there, but shhhh) pearlpaint.com
