you're talking about different things... fresh tuna is pretty expensive. its just the cans that are dirt cheap

  I see. But you can get your precious oils (or mercury) from either, right?

    Not sure about the oils/omega-3, but the fish used to make the canned tuna is generally regarded as a much lower source of mercury compared to, say, the tuna used for sushi, and thus safer to eat.
