When we were living in NYC, I ordered senior formula dog food for our very old dog from Amazon. I received notification our dog food had been delivered, but inside the box was a weed wacker. The tracking number on the dog food notification was the same number as on the box containing the weed wacker.
In the end Amazon told me to keep the weed wacker. We lived in an apartment and we gave it to the grounds-keeping crew, since we had absolutely no use (or space) for it.
