To Transfer Gold
1. Have both of your characters (one alliance, one horde) go to the Booty Bay Auction House.
2. Have the character who you want to receive the gold put any item up in the auction house with the buyout price being how much you want him to receive.
3. Log on with your other character and buyout the item you put up with the other character.
4. Log on with the other chracter. You should receive most of the money that the other character paid, but there is an auction house cut.
ex. I put up a plucked feather and paid 5g for it with my alt, my selling character got 4g 25s.
How To Transfer Items
1. Get both of your characters to Booty Bay Auction House.
2. Have the char with the item you want to transfer put the item you want to sell up in the AH for a low buyout price. (1c, 1s, whatever)
3. Log on with your other character and buyout the item you want. But be quick! If someone else happens to be searching that AH at the right time, they may see your epic being sold for 1s and buy it before you!
Whoops guess it was. Sorry!I don't know if this has been posted before, but....
