This question just came to me while I was buying a subway pass. It’s priced very well, provides a very good service, doesn’t suffer from enshittification, and its price increases very rarely.
What are some other services which people don’t mind subscribing to?
Our art museum is free but for 100/yr we used to get a subscription that got us 4 free tickets per day to visiting exhibits that are normally $16 each, plus free parking which is normally $10 and it’s across the street from a big park with food trucks and activities.
Also, the zoo and botanical garden memberships that offer reciprocity with a bunch of other zoos or gardens.
