4 thoughts on “Why are the number of prices behind the market promotion price in the mall most "9"? For example, 19, 29, 39, 49, 999, 4999 ...”

  1. This is based on human psychological effects, especially consumer psychology. 1. Most people think that odd numbers feel smaller than even, and you can feel it yourself. 2. 9 and 10, 99 and 100 are different levels. It feels like 119 and 120, as if they are much small. 3. After consumption, I feel that there is still money to find. For example, if you buy things 99 yuan, give 100 yuan, you can still find 1 or 1 coin, yes! 4. Many people think that 8, 9, etc. are auspicious. Only one thing is to promote consumer purchase.
