At the exit of the shopping mall or the school gate, many companies are distributing flyers to passers-by. This is not only bad marketing effect, but also makes the streets full of confetti. One feature of this discovery is that when pedestrians are walking, they will not continue to look at the trash cans thrown away after receiving the flyers. That being the case, why waste time and money like this? Why not use advertising bags to print their company's sales advertisements? I think some netizens will ask: If we don’t let people throw it away, can we not do this? Can't we do it by hand? In fact, labor is needed. It's not like a person handing out flyers. Moreover, the cost of a year's flyer far exceeds a canvas bag. So, how come we don't have to distribute flyers to everyone! Here I can think of some ways to make thousands of canvas bags, free bags at the door of each office building, or other businesses, small supermarkets, etc. In this way, people will not throw away the bag right away when they get the bag, and they can also provide packaging. When customers need it, they naturally think of merchants. There is also a handbag that can be sent to some clothing stores in second- and fourth-tier cities. They can provide bags for free, not only to help merchants, but also to run their own company's marketing.
