I got some Screen-shots i'll upload tomorrow that are REALLY funny I've done this for months.
I buy something that has no comparable stats... say a chest armor with 240 vit, 190 int, 3 os. You search stuff like this until you find something with a price gap where there is a cheap one for like 1-5 mil.. and the next one in the list is like 40 mil. I buy it... and raise it up to 30 mil.. I then say in Trade chat Looking to buy 3 socket Chest Armors with 190 INT, 240 vit. no other stats needed, offering 40 mil pm me.... They go into the ah and try to flip it back to me.. ill say i take it.. they buy it.. then i take off because they bought an over priced item off me. It works well if you have 3-6 accounts and can hit loads of trade channels and keep re logging.
The pics are of my ah with pages and pages of bought for 1mil, sold for 15, bought for 1 mil, sold for 15. And one pic of a guy saying "your a fucking idiot nobody's going to fall for that.." another guy agreeing.. then "sold" lol
