Legal analysis: It depends on the specific product model. The price of ordinary masks should be implemented according to the price limit of the local price department. If the price exceeds the limit, you can report it. The price of masks should be within a reasonable range during the epidemic. Those who drive up prices can be investigated for legal responsibility. There are two conditions for "driving up prices" to violate the law: first, fabricating and spreading price increase information; The second is to drive up the price, the price is too high, and the price increase is too fast. Whether it is illegal or not, the regulatory authorities need to comprehensively consider the sales cost of goods and refer to the sales prices of previous or similar businesses for screening, mainly to see whether the price increase behavior exceeds the range and speed of cost increase. However, in the extraordinary period when the epidemic was raging, the country's determination to crack down on price increases was very obvious.
