Like Ed/HK and several others, we feed Kirkland C, R & V (formula below). At the closest Costco 70 miles away it's about $25 (tax incld) for a 40 lb. bag. Puff has been on it for 6 years.
At supper, in addition to her one cup of food, she also gets with it a cup of cooked (previously frozen) green string beans (no salt), a small slice of cooked salmon, 1 G&C tab, 1 Fish Oil cap.
The only "problem" with the Kirkland for us is that since Puff eats only 2 cups a day, the food can get stale and unappetizing for her if left in just the opened bag, So, after much experimenting, I found the easiest remedy is -- as soon as I open a new bag -- to transfer all its contents into ten one-gallon Ziplock freezer bags and seal them.
BTW, "Diamond Naturals" has a similar formula (but NOT plain "Diamond" -- with the introduction of "DN" the plain Diamond became a lower grade food); it's made by the same company that makes Kirkland and those products are widely available from TSC (Tractor Supply) stores as well as many other outlets. See this link if you'd like to locate one near you. http://www.diamondpet.com/dealer_locator/
The Kirkland is also available in a L&R formula but I prefer the C&R because it has fewer rice ingredients.
