Hi! Each fragment cost 85 points, which means 33 fragments would cost 2805 points or 5610 coupons. However, the event allows you to obtain 1050 points free by participating fully for the 7 days, which means it could cost much less =p Hope that helps! If you take into account the 1050 free points, 2805-1050 = 1755 points left, which is 3510 coupons.
