Definition of bind-in

promotional piece with a reply or order form, frequently on card stock, bound into a magazine. The response device portion of the bind-in is usually perforated for easy removal from the binding. Most bind-ins are designed according to U.S. Postal Service size requirements, so that the reply form portion, if any, can be mailed. Some are the same size as a page and include several perforated reply forms. Although bind-ins can somewhat obscure the page they are bound on top of, they also make that page or advertisement more visible to anyone casually flipping through the magazine. Some bind-ins serve as the reply form for a space ad.
