The multiple between Temu's selling price and the supply price depends on many factors, including production costs, market demand, competitor pricing, etc.

Usually, the selling price will be 2-3 times the supply price to ensure that the merchant can make a profit and cover operating costs. However, this multiple is not fixed and will change according to different products and market conditions. Merchants need to weigh costs and market demand to determine the most appropriate selling price to maintain profitability and attract consumers.
