go into diet and health section on this board and right at the top there is a post about "premium foods" . They are on the list. Go to thier website and send them an email asking for them for a free sample. I did this just to try it first with my dogs before I bought a bigger bag. They sent me 6 small bags. MY dogs liked it, however I asked for samples of Taste of the wild (same company) also and my dogs enjoyed that more.
The chicken soup isnt really that expensive compared to some of the better foods Ive seen. They also make can. It has great ingredients in it!!
I found mine at a local feed store. I think petsmart carries it but Im not real positive on that.
