Hey everyone.
I have created something I found to be extremely useful.
What you do is post some Rune of Teleportations (Around 5-10) on the AH for 300g. Post it up there for a day or two. (So if you do it on Friday, take it off on Sunday).
Now, on Sunday, put them all back up for 100g.
What does this do and how does it work, you ask?
Well, people with AUCTIONEER scan the AH and it records that its worth 300g. So when they see it up for 100g, they jump at the chance and buy it, thinking they're getting a steal.
But in reality, you're making TONS of gold for NOTHING.
Ofcourse, there are some people who know the true worth of these and won't bite, but I always sell one or two of them and make huge profits.
You CAN'T get banned for it.
Theoretically, this can be used on other items as well. I think a good item would be an item that many people don't know about, thus will not know its true worth off the bat.
