It's a fair price. I wouldn't pay that much for one, but I have no real desire for one. You ask for market price, well since there is no set retail price, price will fluctuate based on supply and demand. Everyone here would be the main culprits in driving the price up.
I've seen some stands on ebay Australia where the seller started the bidding price at AU $90!!! Total rip off merchant. It's a contentious issue but I believe if you're looking to make a profit from Oakleys you should question why you are into them in the first place.
