Absolute rip-off when you consider the cost of canned mackerel and sardines. I get sardines for 70 cents to one buck a can, and that's real food. Besides, you can eat fresh salmon or sardines three times a week and take some flaxseed oil and be set for the week with omega-3 fatty acids. Throw in other fats that one might eat, such as nuts and seeds, especially walnuts, and you're fine for omega-3's.
Except if you ask Charles Loliquin.
