What does 15 yuan, the highest reward for free food purchase in Pinduoduo, mean? When paying, there is no shortage of money. Don't answer if you don't need it, okay?

What you should say is to buy more food and place an order. In fact, this is just a routine of Pinduoduo. He said 15 yuan was free of charge, but he actually gave you a coupon for 15 yuan after you placed the order. And there will be several denominations. For example, a three-yuan coupon requires you to buy something worth 19 yuan, and then you can reduce it by three yuan. However, when you place an order for the first time, you pay in full. The coupon of 15 yuan will not reach your account until after you place an order. However, these coupons have a threshold for use, so you should read them clearly when you consume them.
