Adobe with Creative Cloud, for example. East West's "Cloud Composer" (for musicians). Apple's iPhone upgrade program. Spotify, Pandora, Apple Music, Amazon Prime, Netflix, and Hulu will keep you entertained.
Dollar Shave Club and Harry's Razors will keep your beard at bay, what with their duelling advertisement campaigns and monthly delivery plans. Keepitcut and Unlimited Hair Cuts will keep you looking good. Dozens of health clubs will let you buy a subscription (errr, "plan") and not work out. Heh.

After you're done not working out, Hellofresh and Greenchef will make sure never get hungry. You can vape with a subscription.
I just heard today that there's a toothbrush subscription: Quip. Their tagline is "Covered for life *"
* While on a refill plan
So now this made me look for something (anything) for which there is NOT a subscription. Underwear? Nope, subscription. Condoms? Many competing subscriptions! You can even buy a subscription for batteries and car tires!
I wonder, can I buy a subscription of subscriptions?
What weird subscriptions have you come across?
