It's a long shot, but here it is. I'm willing to pay 5500 gold for each of the HM. This will result in 456500 gold for the payment. I will however, top this up to 470000 to round it up to a nice number. Not all that interested in making many small deals to make it up to 83 hardened metal, I want to buy in bulk.
