Gome, Suning and other 3C stores have national channels, with many stores and good location, which can be easily reached by consumers. For manufacturers, it is only necessary to sign a national sales agreement, which eliminates the trouble of negotiating and signing one by one.
I don't know much about clothing, but what is certain is that clothing consumers pay attention to experience and shopping environment, so clothing manufacturers do more shops in channels.
Of course, there are other advantages in the form of specialty stores. Whether it is home appliances or clothing, we all like this channel, so I won't elaborate here.
