The selling price and strike-through price of Douyin Store should be reasonably priced. Reasonable pricing can increase customers' enthusiasm for purchasing on the one hand, and ensure the store's profit on the other hand. The selling price is generally lower than the strike-through price, otherwise it will make customers feel too expensive and unwilling to buy. At the same time, the selling price should also be determined according to the actual value of the product and the market conditions. If the selling price is too high, it will cause customers to question and reject the product, affecting the sales of the product. If the selling price is too low, the store's profit margin will be lost, affecting the sustainability of long-term operations. Therefore, when setting prices, stores should comprehensively consider the actual value of the product, market demand and customer psychology. Reasonable pricing can ensure a win-win situation for customers and stores.
