Keeping Fish Oil from Going Rancid
I bought some bottles of Carlson fish oil and cod liver oil. But I bought way too many. What's the best way to ensure that they will not go rancid or become oxidized?
Supposedly, if you store fish oil (especially fish oil capsules) at room temperature, they can go rancid. Damaged fish oil can induce oxidation and incur oxidative stress in your body, supposedly ... one of the biggest argument against taking fish oil in the first place and eat fish instead.
So store in the fridge? Freeze them? Store in a cool, dry place away from sunlight like you would store your EVOO? What's the best way?

Well ideally you wouldn't buy more quantity than you can use before they go rancid
Refrigeration is a minimum. My guess is freezing is even better for excess quantity but I don't know the impact of freezing on PUFAs. My guess is that if they can flash-freeze salmon as its caught, and no one discovered damage, its probably ok...
I've had a bottle of 400 Kirkland Signature (I think that's Costco brand) Omega 3 (1g) softgels for nearly a year and half and they still taste\smell fine, not a single broken pill either (except that one time I left one in my pocket all day, and leaked, leaving me with smelly jeans 4 washes later).
I've had several bottles of Mercola krill go rancid on me within 3 months. To their credit, they replaced them, no questions asked. Still, two times is 2 too many.

Were you storing them at room termperature? I've stored mine at room temperature but away from sunlight. Just started refrigerating them today.
