Recently, Miss Liu complained to the industry and commerce department that she had bought a pair of old sandals in a shopping mall, but she did not wear them in a few days. When she found the salesmen asking for a refund, they refused to return the shoes on the grounds that they were special products.

After mediation by the industrial and commercial departments, Miss Liu bought a new pair of shoes.

According to the three package method of leather shoes, only when the words "defective" or "processed goods" are marked in advance, consumers do not have to be responsible for the quality of goods purchased after knowing the situation.

For goods sold on sale, sale or promotion, businesses must assume responsibility for quality assurance.
