Well
I hope the seller didn't tell you he had a firm offer at 6k, because I withdrew that offer on Tuesday.
So if he said that to you, it wasn't true. I saw no other evidence of offers beyond mine, at 6k until I was pointed to your 6.3k bid.
Me thinks you got misled, just a tiny bit on the sale, but overall I am sure you are happy with it.
At the end of the day, I wouldn't have paid more than 6k because that was an overpriced bid to secure the buy, and it didn't fly. So all good.
So, for the first rare loot for this player, he was a slick seller.
Name of the game!
