A Family Plan which cost US$34.99 divided by 8 people in which 5 suckers need to fork out S$9 each and the other 3 only need to come out with $1 each...A very fair system for you to pay more and can be kick out of the family group at any time by the family admin...

The Nintendo Switch Online membership will automatically apply to everyone in the family group, including people that are added to the group later.
The purchaser does not have to be the account admin for the group. However, only the account admin for the family group can add or remove people from the group.
If the person that purchased the family membership leaves the family group, the other members of the family group can no longer use the features of the Nintendo Switch Online service (including Save Data Cloud backup) until they become a member again.
If a person that did not purchase the family membership leaves the family group, they will no longer be covered by the service.
