Economies differ and if you're new to the auction house, it can be overwhelming. Lately when I want to sell something, I have to see if anyone else is selling it also and figure out what the average price is so I can put up an item with a reasonable price. If no one has the item up, I have to resort to googling and other tactics.
Is there a tool which just tells you when you're creating auctions what it sells best at or something similar? Any kind of add-on that is easy to use and not cumbersome?
