Btw, OP:

Putting up a NQ item with a XXXX3 prize works wonders if you want to attract customers to your bazaar And sometimes you can even scam someone into buying that NQ item at a much, much higher prize.

And the best thing is: it's not even possible to blacklist retainers. Since people can't remember all the names manually, they will inevitably fall into the same trap over and over.

(Note: Just expressing my displeasure with the current system).
