Excuse me, do you want to ask, "Why is the price difference between buying probiotics in Duoduo and JD.COM so much?" ? The reason why the price of probiotics sold on these two platforms is much lower is that:

1. Channel cost: Pinduoduo is a social e-commerce platform, which usually reduces the marketing cost of merchants and enables them to sell products at lower prices. JD.COM as a traditional e-commerce platform. The channel cost of COM is usually high.

2. Sources of goods: The sources of goods sold by merchants on different platforms may be different. For example, Pinduoduo may offer cheaper products, but they may come from small domestic factories. JD.COM may provide products with more reliable and well-known brands.

3. Sales method: Pinduoduo group purchase sales. When more users participate in the purchase, the price will drop accordingly. JD.COM, on the other hand, is a single purchasing mode, and the price usually does not decrease with the increase of purchasing volume.
