Ok i did this dupe methode on a live realm it relly works its duping money straight ok this is how its done....
1.get a on one of your 60s or someone with a lot of valuble vendor iteams.
2.Sell them ALL and send all the money to a diffrent character
3.Delete that char imeaditly after you send the gold and log
4.make a new guy and say that you little or big bro got on you account and sold everything and deleted him.
5. in about 8 hours a GM will say log off and restart your computer when you log on your charrter is retsorted with all the money and iteams/gear
6. its kinda funny how nooby GMs are because they dont take the gold you sent your other char lol =) have fun with it
oh BTW i tested this on a friends char who stoped playing wow sold everything on him that was sellable made about 3000gold (he had all might gear) and sent all the money to my guy then told a GM that my little bro sold everything then deleted my guy they restord it within 8 hours and i came out 6000gold ahead =) (because i then again resold everything and sent the money to my guy) ask if you need help with any part of it i dont know how to make movies so plz dont ask
