If you raise the price, you can ignore IP.
But if you want to reduce the price, it must be consistent with the IP at the time of registration.
Otherwise I can't change it. This is the problem I encountered. I forgot what IP was when I registered.
It is difficult for me to change the price now. .....
If it is the same, click I want to sell, then take it off the shelf and set the price on the shelf.
Hehe, typing is so tiring! thank you
