I recently bought some dry cat food from Amazon. One of my cats immediately got a massive skin infection that cost >$400 to cure. I can't prove it was from that but this is an indoor cat who has no real exposure to anything else that would have been different.
Needless to say, I totally agree with not buying anything that goes on or in a living thing.
