Let them know how their life will be easier, happier, or more successful after they have bought from you. Instruct the potential customer how to buy what you sell. Include your name, phone, fax, e-mail, web site, location, or hours and anything else that makes it super easy for the prospect to contact you. It costs no more to have your flier copied on colored paper, so choose a color that grabs attention but won't make your copy hard to read. Lighter colors are best.
Many successful fliers have no pictures.
Line drawings are easily copied. A photo needs to be half toned first to give a clear photocopied reproduction. Your copy shop can prepare the photo for you. Also pay attention to the quality of the copier. Some of the newer, better maintained machines turn out photo copies that look as good as offset.
