Please introduce your cargo logistics plan. In fact, if you want to avoid the commission of the supermarket, can you set up a separate sales? I wonder if the brand you represent allows this?
Besides, cooperation should be win-win. I don't know how you plan to cooperate. For example, children's clothing is provided free of charge. Children's wear at a discount? What do kindergartens need to do?
It is difficult for you to write a plan with so little information.
As for the mode of cooperation scheme, please refer to the following links.
