i dunno if im trusted enough but i can sure help get your method down.
First off what combat lvls are they if there both med crater or both low crater it easy even high crater. What you do is you have one guy on account with stuff you want to transfer via bh to other accoun he goes into bh finds his location using map or compass and then logs the other account comes finds his spot u step over him then when account with cash logs in kill then quickly hit door as he hits 0 hp make sure he dies though then go back in through crater and run back to spot to pick up no penalty.
