a personal friend of mine buys nps from me and I just get her to "snipe" an item from my shop for 1np then sell it back to me for full, via auctions or whatever
but you need to have an item worth the nps value for that to work
Did know there were flags tbh. I do ETS and 2m NP per trade...up to about 10 trades.
If its more, I do it through auctions ONLY if both accounts look decent enough. Noone questions auctions unless one of the accounts is shell-like as so many high end sales go on and TNTs silly limits mean some people have to do junk auctions.
Never been iced since I started transferring NP and I do it really...not safely according to this thread. Maybe I have been lucky, or maybe they just don't care anymore
