I think there should be an item auction house.. Because if you do that, there will be another use for buying an item finder/Dowsing Machine. If you have an extra item that you don't need or if you want to sell like a tm06 or pecha scarf etc.., you will be able to auction it at an Item Auction House. I hope this is a good idea and helps people:) P.S. Also it will be better because if you sell an item at the item market there can be only be 20item per page, so you would have to keep removing and adding it to the page again, because flipping through 10 page will take too long.(if 10pg.+ you will have to search it). Also in the item market it would remove/delete the item if it doesnt get sold in a month so... this is why it would also be a great idea to make an Item auction house!:D

2/10 because if i auction a toxic worth 4500 coins, i wont get 4500 coins from it

Well u will never be able to sell it in the item market
