江阴张大爷花27000元，竟买了这……

Core Viewpoint - The article highlights a case where an elderly individual was misled into purchasing health supplements during a free tour, raising concerns about consumer rights and the responsibilities of businesses in advertising and selling products [1][8]. Summary by Sections Case Introduction - In August 2025, an elderly man named Zhang was persuaded by peers to join a free trip to a Lingzhi (reishi mushroom) base in Anhui, where he was influenced by a so-called "expert" to buy Lingzhi powder worth 27,000 yuan [1]. Handling Process and Outcome - Zhang provided the actual product and a handwritten receipt to the consumer protection committee, which confirmed the authenticity of the receipt. Zhang argued that the product was ineffective and demanded a full refund, while the merchant claimed that effectiveness could not be proven without evidence [2][3]. - Initially, the merchant resisted the refund due to financial interests. The consumer protection committee facilitated multiple rounds of mediation, emphasizing legal consequences for refusal and encouraging both parties to consider each other's perspectives. Eventually, they reached an agreement where Zhang returned unopened products and received a full refund [4]. Case Analysis - The merchant's actions of enticing elderly consumers through a "free tour" and potentially exaggerating the product's benefits may have violated consumer rights, particularly the right to truthful and comprehensive information about products [7][8]. Consumer Advice - Families should enhance awareness of scams targeting the elderly and provide informed guidance on spending and health-related purchases. Elderly individuals should remain rational when faced with "free" offers and consult family before making financial decisions. It is crucial to retain receipts and invoices for potential claims [9].
