If your target audience is busy and mobile, the best way to reach your customer is to integrate your advertisement into their lives where they dine, shop, and travel.  Meet your marketing objectives by placing your advertisement in a shopping mall or retail location right along with consumers when they are most receptive to making a purchase. Capitalize on a captive audience as they wait in line at passport control, wait to board a flight, or wait for their luggage at the baggage claim carousel at the airport.  Wait times make for lasting impressions and greater impact: your target audience will spend a longer amount of time concentrating on your ad than they would on a 30 second television commercial.
The smaller size of indoor sign displays are more cost efficient than larger outdoor ads, which is perfect for a marketing budget of any size.
