All for 1 ref seem to be sold out. Plenty for sale @ 1.33. I might have to agree with you.

I would agree with price range from 1 Refined to 1.33 Refined, These sell pretty good at 1 refined but also sell for 1.33, but the thing is that there's not many traders selling these so you kinda can sell it overpriced and people will still buy it, another good indicator is that wharehouse always have low stock on these.
