If the price of my ordered items changes, will the total billing amount also change?

If the item price has increased when we make the purchase, your billing amount will not be changed.
However, we will cancel your order if the price increase exceeds 5% compared to the price when you placed the order.

If the actual purchase price is lower than your request, the billing amount will be changed to the actual purchase price.
In this case, if you have chosen Alipay as payment method, we will refund the price difference after we complete the purchase.
