• Member can manage their subscription (Pause, Cancel, Skip, etc) — lets them pause/cancel/skip it themselves.
• Member can select included meals — lets them pick their own meals within the plan.
• Disable purchasing extra meals — blocks the member from buying extra meals beyond the plan.
• Disable extras upselling — blocks add-on/extras upsell prompts for the member.
• You pay this member subscription — bills the parent account for this member's subscription instead of the member.

Turning on "You pay this member subscription" reveals a further list of modules the member is still allowed to check out in on the parent's account (e.g. retail, wholesale) — each is on by default.
