I think there may be many reasons for the price increase in disguise. There are some things that businessmen hold simply to make more profits. Most businesses have seen consumers' great dependence on them, and disguised price increases have forced consumers to accept them. In addition, it may be forced by the form, such as raising prices and increasing costs, but if the direct price increase may make consumers dissatisfied, then the price increase will be disguised. And so on, there may be other specific phenomena, which cannot be generalized.

The meaning is purely personal!
