If you have a child going into 3rd, 4th or 5th Grade, the PS 321 PTA will take the work of buying school supplies off your hands! We work with Mulee, a Brooklyn- based company, to provide teachers and students with the school supplies they need to start the year. Each supply set is $45. That’s 33% less than the supplies would cost at Staples and 30% of the proceeds go to the PS 321 PTA. The flyer with information about ordering school supplies for the upcoming year are sent home in mid-May and orders need to be placed before the last day of school.
