Joint purchase is a list, such as 10 yuan. You can buy as many as you want and distribute the bonus in proportion after winning the prize. Customized follow-up means that every time you like the list sent by that person, you set the follow-up, set the amount yourself, and automatically initiate the list with him in each issue. Divide the bonus according to the proportion of the quantity you buy. Typing is very tiring, I hope it will help you.
