I purchase the NB @ Petco. Evenger's I get from the doggy boutique in town and it really is not that expensive about $1.25 can and then I mix the entire can with pumpkin. Natural Balance comes in many different flavors but I use the Limited Ingrediate because Pebbles has allergies to chicken and grains.
Also, check in the health and diet forum here and there are links to many different foods and they all offer free samples.
