This way is actually very common, attracting others with a little interest, and then gradually falling into deeper and deeper pits. I did the same thing when I was looking for a part-time job, and it turned out to be another way to present bills. In fact, the general content is similar, and the studio uses this low price to attract those people. In fact, college students are the most easily fooled, because they have less experience and it is difficult to distinguish the advantages and disadvantages of this model. If you can't stand the sales promotion of waiters, you will buy some value-added services. Through this model, college students spend a lot of money invisibly. Admittedly, in such an environment, college students are very uncomfortable.
Therefore, the routine behind this low-cost photography is to do appreciation service, attract a large number of users at a very cheap price, and then do appreciation service. It is not 19.9 yuan that makes money, but those value-added services. The price of going to the set is actually relatively high. Under normal circumstances, this model is definitely profitable.
