All I can tell you is the sample size was about $3 for a 2.5 lb bag . I'm sure someone else can tell you more, but it was one of the most reasonably priced, higher quality foods I found (but has fish in it,and my cat has a fish allergy ). My kitten really liked the kitten formula, though.
I am expecting some HealthWise by Innova to arrive next week from PetCo. It is the same price as the Chicken Soup and it sounds like a good healthy food too. With the 20% off coupon I had, that pretty much covers the shipping so it all evens out.
