In the business circle of a living area, there is a square with a relatively large area. During the day, some businesses are usually doing publicity and performance activities. In the evening, 90% of the time is free, and it becomes a leisure place for residents to walk. One boss saw the business opportunities inside and bought more than a dozen electric toy cars for children to play. The price is 10 yuan for 30 minutes, and this space is free to use, so except for the electric car and the cost of electricity, the rest is profit. The boss's business is good and bad, but never when a dozen cars are rented out, the overall business is very general. Later, at the suggestion of a friend, the boss adopted a series of marketing strategies. When there is almost no free time for more than a dozen electric cars every day, the business becomes very good. What kind of marketing strategy is it? First, make an advertisement sign and write: 'Dad, Mom, I like driving. 'Second, divide the three electric vehicles and indicate that they can be used free of charge. As long as the three vehicles are idle, anyone with children can use them free of charge. Third, change the original 30-minute 10 yuan price to 5 minutes 3 yuan. Fourth, prepare some small gifts such as small cartoons and balloons, and send them to parents with children in the past, whether they rent a car or not. Fifth, get in touch with the surrounding kindergartens, rent toy electric cars for free, and hold children's racing competitions regularly.
