Pet Stores on the Net

I buy most of my pet supplies over the internet.  The prices are generally 30% lower than the stores, you don't have to pay taxes, and shipping is minimal (if you choose UPS ground).  It's a lot easier than lugging a 40lb. bag of dog food home... I have it delivered to my door automatically every month through PETS.COM.  

My favorites are PETS.COM (the one with the sock puppet) and allpets.com.
