The group owner said that some new merchants will reduce costs in order to increase sales. So they will issue some coupons to the group owner. Someone in the group happens to need to buy something, and gives the order number to the group owner. The group owner and the merchant earn commissions. I don’t know how much the commission is.

Customers buy discounted goods, the group owner earns commissions, and the merchant increases sales. It’s a win-win situation.

I would also like to add that some things are indeed cheaper than buying them from Taobao. You will only buy when you really need them, not blindly.
