Flyers are handed out on the street (a practice known as "flyering" or "leafleting"), distributed door-to-door through the mail, posted on bulletin boards, put under windshield wipers of cars, given away at events or on the street, or affixed to telephone poles, walls, or other surfaces. Bulletin boards are found on college campuses, in cafés, community meeting houses, laundromats and small markets. Cheap to produce, contemporary flyers are frequently produced in 300 g/m2 glossy card, whereas a leaflet might be produced on a 130 g/m2–170 g/m2 weight paper and can be a very effective form of direct marketing.
