I would highly recommend Pet Club based on their food prices alone. I feed my dogs Natural Balance and for a 30lb bag Pet Club is roughly $15 cheaper than Petco. They also offer a buy 10 bags get 1 free deal for Natural Balance. They have a great selection of other high quality dog and cat foods - stuff you can't find at the larger chain stores. Lots of organic and RAW options. You won't find the cheap stuff here, Pedigree, Kibbles & Bits, eeew.
They also have a great selection of treats and they are reasonably priced. If you are looking for dog beds, bowls, leashes, collars etc you are better off looking elsewhere because I have noticed they are a bit over priced at Pet Club.
Most locations also offer low cost vaccine clinics several times a month.
I did deduct 1 star for customer service. I realize working in a slow pet food store can be boring but sometimes I feel like I am bothering some of the girls at the register - they are nice don't get me wrong but they are just not outwardly friendly. Also a few times I have purchased more than 1 30 lb bag of food and they offered no help in getting the bags to my car. I had to take one bag to the car then come back to get the second.
