Selling Dragon Quest items

Hi,

I was wondering something. Alot of players are selling their DQ items, but when I am doing the same, nobody is buying my items.

I am pretty sure I am not overselling them, i am under de prices that the rest is selling them for.

Has anybody got some tips for me?

Tips to make some money on other items are also appreciated. I am kinda new to this game.

Thank you in advance!
