I shop at Petsmart over any pet store for my dog and their online website makes it even more convenient to find what I need. I can also use my PetPerks rewards card online for better deals and special features. The website is easy to use and have many different brands of what I'm looking for. I use Hill's Science Diet Active Longevity Mature Adult dog food, which is not available everywhere. Petsmart has it. They even have buy it online and pick it up in the store, saving time on shopping around in the store and guaranteeing it will be there for you. Or they do offer free shipping on order $49 or more, which is easy to spend. I can save gas by ordering online and having it come right to my door (saves me from carrying that huge bag of dog food). What's also great is they have featured articles on pet nutrition and other helpful tips. As well they can connect you to obedience classes, adoptiion, and boarding in the store closest to you.
