don't know if this has been posted or somet, but hey we will see.
Anyway you find a victim and then go to the mailbox and maybe send some water, but don't send the water, make it COD put the amount at a reasonable amount maybe 10-50g or somet, and send it to that player. once they receive it if there don't look, I don't most of the time, they will see the 50g and the item and think they get both. were in actual fact its cash on deposit. so the second they deposit the item into there bag it sends you the money! lol FREE MONEY!
have fun.
