It’s not their fault that you’re using your hair clipper wrong. 
Heck, I just ordered a new plastic line for the ice maker in my refrigerator and it’s apparently a “Lawn & Garden” item as well.
I was alarmed that the email heading said 4 pharmacy items had shipped, since I don’t use their pharmacy, but the full text headibgbsaid something like “pharmacy & supplements.”
My shipping confirmation for my last auto ship, which contained a replacement filter for my air purifier, daily shower cleaner, and bird seed, described these items as “1 Electrical and Heating, 1 Essentials, and 1 other item”.
