My extended polycule is vast(as they tend to be), but the core "family unit" of us consists of around 5-7 people. In that group, we're fairly kitchen table, and are planning to move in together this year. (Yippee!!)

Recently we started sharing services here and there. Google play games family accounts, and AI Chat subscriptions.

What other services are out there that you've shared with family and/or polycule members to save on money?
