My girlfriend and I came here after adopting a cat at the Champaign Humane Society.
The staff is great, they are very helpful and accommodating. There are only a few of them though so you may need to approach them for help.
The selection is not so great compared to Petco, Petsmart, or Amazon. They have the major brands, they just don't have all the varieties those major brands provide. However, their selection for dog food is on par with the major stores.
Pricing is close to the major stores. While maybe half the items are more expensive, it's only by a few bucks. But it does help to buy here at a local store instead of a chain. Plus they have coupons.
