I was stupid last week I nearly got a macbook pro for £480. It was advertised for £600 because it had a dent in the casing and no install disks. I was talking to him on the phone saying I can pick it up (it was 40miles or so away) and he said he will sell it for £480 for cash and pick up.
As I was on the phone someone bought it for his asking price. =( I couldnt complain as I made the mistake of not saying to him sold before the buy it now was placed.
