What are Some Pet Stores that Don't Sell Animals in Michigan?

I recently decided to stop shopping at pet stores, for animals and supplies. This is because I do not wish to become a supporter of those terrible mills. I don't want my money to be used to put animals through so much pain and misery. I am having a hard time finding pet stores that do not sell any animals. Absolutely no animals. No cats, no dogs, no mice, no ferrets, no rats, no fish, no birds...no animals. Just supplies. So I was wondering if anybody here knows any pet stores that only sell supplies and no animals. Or at least pet stores that don't support these mills. Preferably pet stores that are scattered around Michigan (at least a few places here) so that I might find one we live by. Any help will be very much appreciated.

Thank you!
