Merchants can put similar products of different specifications on one product, and the prices vary greatly. When making a guide map, the merchants will definitely attract you to click in and buy it at the cheapest price. You need to choose the cheapest specifications as the cheap price tag of the merchants.
In fact, this is a marketing technology, and some goods have different attributes, resulting in multiple SKUs. For example, I sell snacks, a 70g pistachio 15 yuan, and a 200g pistachio/32 yuan, so that Taobao will display a lowest price, and when you click in, you will find that the price you want to buy is different from what you see.
There is also a black technology that belongs to the great god. I don't know, I dare not ask. He can set the price very low, and the price will be very expensive if you click in. But once it is discovered by Taobao system, it will be closed.
Other information
The general platform has strict requirements on products for reference activities, and it is not allowed to change the price for a certain period of time before the activities, instead of many people think that products for official activities have specific labels, and many products that are not eligible to participate in the activities also have fake labels, which is easy for consumers to be confused.
There will be advance notice for discounts on active goods. If you plan to buy it, you must see the time clearly. The price reduction of ordinary goods is arbitrary and there is no special regulation, so luck is also very important. Search for the same type and compare it. You can also buy more collections in advance and wait for the merchants to give you a discount!
