If the product price exceeds the demand, there is usually a flat price difference on each gradient. For example, Pu 'er tea, Taobao's lowest price is 9.9, and each plant also has 88. 1 10,000 trees.

However, it is precisely because of this oversupply that the quality of Pu 'er tea is uneven, and the price may be directly proportional to the value, but it may also deviate from the value range and appear abnormal. The goal pursued by the consumer market is the rationalization of prices, that is, a penny for a penny.

However, usually the price is directly proportional to the value, and the higher the price, the higher the quality of the product. It is easy to buy tea with matching quality without pursuing the special situation of extremely low price and extremely high price.
