If Temu sellers accidentally click on the price reduction, they can take the following measures:

1. Contact the buyer immediately to inform them that the product has been reduced in price. If they cancel their previous orders and repurchase the reduced products, they can give them some discounts, such as free shipping or some gifts, which can increase the satisfaction and loyalty of buyers.

2. Check whether the product price is reasonable. If the product price is too much lower than the cost price or the market price, you can consider resetting the price or contacting the buyer to explain the reason.

3. If the seller thinks the price reduction is wrong, you can immediately contact Temu customer service and ask them to help restore the original price.

4. If the seller finds that the order volume has increased after the price reduction, then you can consider adjusting the price strategy and lowering the price appropriately to attract more buyers.

5. If the seller finds that the order volume has decreased after the price reduction, then you can consider re-evaluating the product pricing and promotion strategy to attract more buyers. In short, if the seller accidentally clicks on the price reduction, don't panic, but calmly analyze the situation and take corresponding measures. At the same time, sellers should also pay attention to the rationality and effectiveness of pricing and promotion strategies to achieve the goals of sales growth and profit maximization.
