If the price is marked incorrectly, does the merchant need to trade according to the price?

Merchants mark the wrong price, whether it is an unintentional mistake or a deliberate stunt. The court needs to judge according to the specific circumstances. In principle, merchants should provide products at the agreed time, manner and price. However, Article 147 of China's Civil Code stipulates that the actor has the right to request the people's court or arbitration institution to cancel the civil juristic act based on major misunderstanding. So if his bid is low, he may cancel your transaction.
