First of all, Maotai 1499 must be a member of JD.COM Plus to make an appointment. If not, you must open a member of plus. In this way, you virtually gave JD.COM consumption.
Second, attract traffic. Every day, hundreds of thousands of people make an appointment to snap up, so this traffic is very huge. There must be a limit on how many bottles can be sold in each region every day, otherwise people who make an appointment can grab them, and JD.COM will definitely lose money. But he only sells a specified amount every day, and he won't lose much compared with the flow.
Thirdly, in fact, 1499 Maotai is sold not only in JD.COM, but also in some supermarkets (such as Wal-Mart and CR Vanguard), but how much do you have to spend? This is actually a principle that allows you to spend more on my platform.
To sum up, selling a few bottles of low-priced Maotai in JD.COM can attract more tourists to spend, and this transaction is cost-effective.
