You can go to their websites and type in your zip code and find the closest store available that sells it. You'd be surprised at what stores probably sell it.
I fed Innova to Jackson for a little while and he seemed to like it at first but grew tired of it very quickly. He's a very picky eater though and now he's been eating Nature's Variety Instinct for 2 months and LOVES it. It's his favorite food, by far.
Artemis sent me a boat load of free samples of the puppy food, it was literally a box. I got like 10 little bags. So I'd recommend requesting some samples from them.
