Changing posters in a professional poster holder for retail effective advertising is extremely high in terms of return on investment (ROI). Drive sales through product lines or departments by highlighting with well positioned point of sale messages. Have you an event /holiday calendar which changes your poster campaign for St. Patrick’s Day, Easter, Mother’s Day, Holidays, Christmas, etc.? Reach consumer buyers with accurate low cost messages, if you don’t tell them, how will they know! Again the design is critical…killer design, pays off.
