HOME AND GARDEN SHOW PARKING LOTS. If you can't afford to rent a booth you can still display your company to all the people who go there. How? By putting advertising on their cars in the parking lots around the trade fair center! If you printed up a few thousand gift certificates and left one on each window of every car in the area you would reach the same people as if you rented a booth in the show. This would probably cost about $100 compared to several hundred or even thousands of dollars for a booth.
