Abalone, a high-end seafood, is being sold at low prices on online markets in Vietnam, with wholesalers like Nguyen Van Tu selling it for as low as 450,000 VND per kg, compared to the standard retail price of 600,000 VND per kg. The low prices are attributed to the sale of domestically sourced abalone, which is currently half the price of previous years due to a disease preventing export. However, concerns have been raised about the quality of imported abalone sold without proper documentation. Meanwhile, Tran Van Phuong, who imports frozen live abalone from China, assures the quality of his products due to full paperwork. The article emphasizes the importance of consumer caution when purchasing seafood online, particularly given the price discrepancies and quality concerns.
