There is currently a "trick"/"scam" going round (as of 22/07/17) where people say "selling 7m item for 4m" and try to sell the Gemstone hauberk for 4,000,000 gp. The [[Grand exchange]] price lists this item at ~7,000,000 gp but it actually sells for around 1,000,000. The victim will lose ~3,000,000 gp.
