Check the actual change you paid to see if it is less than the purchase price. General payment reductions will not reduce the purchase price, but your actual payment amount. The price of the product will not be reduced, only your actual payment amount may be reduced. You can check your purchase and payment records on the Douyin change interface.

I used Douyin change to buy something, but the purchase price did not decrease. However, Douyin change showed that the product had been purchased and used. What does this mean?
