(Ya sorry I'm a "leecher", signed up then never got back on after like four days of doing stuff.)
I searched the forums and didn't find anything sooo.... sorry if this is a repost.
O.K. This may seem a little bit obvious and maybe just for my server, well this is
how i made about 100g by selling something that is 40s from a vendor. This is also mainly for horde characters.
First of all, go to Booty Bay and buy
Parrot Cage (Cockatiel) - Thottbot: World of Warcraft . Then say
"WTS Parrot PST" in trade.
AVOID HAVING TO LINK THE BIRD!!!! When someone messages you saying how much. Tell them to offer. Accept a good amount but don't go extreme. Then tell them that you are far away, or have to go real quick and you will C.O.D.
They will usually just pull the parrot out of the mail without realizing that it isn't the Green Wing Macaw from Dead mines.
This will work majority of the time and is quick gold. I had two people send it back out of about ten so far.
I have made about 300g out of it. (Which is a lot for my realm and level of 25).
Hope this helps and might not be good if you have a real high level character.
