My Printer runs them 3 up on 18 X 12 card stock and then cuts into 6 X 12 to fit the Post office size requirement for EDDM. I am not sure if it is the size or the Contend, but people are keeping these fliers abd calling at later dates. BTW I only do Pest Control. That be an other reason people are keeping my post cards compared to Mowing Fliers. .
