if you only wana xfer around 400-1m then party room wont be that stressing......if you want to xfer huge ie 15m+ check the runescape guides section people are selling working guides to xfer
Depends like some people up there said use guides.
I suggest Party Pete's for 0-4m trades and for anything higher I cant help.
I think you could also use Eye of Newts ( Might have been fixed already )
