Rancid Flaxseed Oil...?

I have bought four different brands of flaxseed oil now, some refridgerated, some not. I tried all of them right when I got home and without exception they were rancid. Does anyone have the same experience? I am not looking to alternatives to Flaxseed Oil, I know about them, but I wonder if there are brands/places that sell them where the oil is not rancid? Thanks
