I can sell you 855 PTS, but we can start from the 300 PTS first.
So 300 PTS * 0.002 = 0.6 BTC.

Or we can use bytemaster's escrow(fee 5 PTS) and you buy all at once. I can pay the escrow fee. In this case:
850 PTS * 0.002 = 1.7 BTC
EDIT2: I might be trading with another person, so I'm cancelling my offering for now
