You can join any party, but I would recommend to look for party with 4 people, or more to get maximum discount on your monthly bill. If you do so your monthly bill will be reduced from 40$ a month to 25$ a month if party at least 4 people total.
You join an anonymous group of people to get discount. You are not connected to each other, everyone is responsible for their own bill without affecting others in the party. Here is more info:
You or anyone are welcome to join my longtime stable group. We are well past the $25/month threshold.
