good convenience but with added expense and mediocre customer service
Invaluable provides convenience of accessing many auctions houses around the world. But invaluable charges roughly 5% higher bidding premium, does surprise price increases AFTER winning an auction, creates some were billing issues for auction houses and their customer service isn't readily available and doesn't answer issues directly. The convenience is 5 stars but the nickel and diming and problems are 1 star so 3 stars is an appropriate rating. I also had an auction house lose two of the items I won and still hasn't refunded me.
