Whether it is JD.COM, Taobao or Pinduoduo, everyone feels that the delivery speed is getting faster and faster in recent years. And like 6 18 and double 1 1, the delivery speed is also very fast. It can be said that it is a second delivery. I just placed an order one second and will send it to you the next. I may receive the goods in less than a day. The delivery speed is fast because we don't give everyone a chance to return it. Because someone bought something at Shuang 1 1 on impulse, they found it cheap and affordable, so they placed an order. However, after calm thinking, I decided to refund. Therefore, in order to avoid this situation, the delivery speed will become faster and we will not be given the opportunity to refund. Moreover, the double 1 1 promotion activity is deeply loved by everyone. Therefore, during this big promotion activity, it can be said that the express delivery is full. Then, in order to earn more money during this activity, the merchants will try their best to improve the logistics speed, not to let everyone wait, to satisfy the hearts of many people to receive goods quickly, and at the same time earn a lot of money, which will not be dragged down by logistics reasons. That's why I think the delivery speed of double 1 1 is fast. However, I would like to remind you that some double 1 1 activities are really cost-effective, but some businesses are very dark, and they will raise the price of goods in advance, and then lower the price before double 1 1, which makes people mistakenly think that it is cost-effective. Therefore, when you buy goods at Shuang 1 1, you must not be cheated and keep your eyes open. At the same time, although double 1 1 many goods will be greatly reduced in price, which is more cost-effective. However, everyone must spend wisely, only buy what they need, and don't spend indiscriminately.
