What is an affordable good brand of canned cat food?

If you're looking for a good quality cat food that's cheap, Whole Foods has some excellent generic cat food. It's cheap, but made with all-natural/organic ingredients, and the first ingredients are meat-based. It isn't the highest quality cat food, but in terms of bang for your buck, it's fine. It's the equivalent of a human being eating tilapia instead of smoked salmon; you still get the basic nutrition needed without unneeded additives, but it's not as "high end" as its pricier counterparts.
