Treating an unusual suggestion like it's normal items? That's new.

But it's wrong.

You will need 2 sales at least.

The QS regulation is not considered a valid sale, and two people are selling at 15 keys because they had duped at the bottom and my clean and I sell it for 19

You have to close it

there are a few sales:
