Legal analysis: Is it true that the so-called "special goods are not returned or exchanged", and is this behavior of merchants legal? Lawyers said that discounts and special prices are normal as a means of promotion for businesses. However, some merchants take advantage of the fact that many consumers don't know the truth or have a weak awareness of rights protection, and there are some problems in the regulations. The stipulation that "special goods are not returned or exchanged" can be regarded as a format clause if consumers explicitly inform them when they buy them, but there is also an important premise that there is no quality problem with the discounted special goods.

Legal basis: Article 7 of the Law of People's Republic of China (PRC) on the Protection of Consumer Rights and Interests, consumers have the right to protect personal and property safety when purchasing and using commodities and receiving services. Consumers have the right to demand that the goods and services provided by business operators meet the requirements of protecting personal and property safety.
