Bind-in cards are cards bound into magazines with saddle-stitch binding or perfect binding. Publishers may sell these cards to advertisers or use them to advertise their own magazine. Many magazines find bind-in one of the most cost-effective methods of gaining new subscribers. Publishers may bind in a single card or a page of cards which may be separated along perforated edges. These cards promote only the magazines in which they are bound.
