🐦 About the early-bird price
- Who gets it: the first 100 paying families, or until December 31, 2026 — whichever comes first. Only for families that have never had a paid membership.
- Locked in while you stay subscribed: $9.99/month or $99/year, and your price never goes up as long as your subscription keeps renewing.
- Cancel and it's gone for good: once your subscription ends, the early-bird price can't come back. Joining again costs the regular price: $14.99/month or $149/year.
- Cancel any time online. You keep access until the end of the period you paid for. Memberships renew automatically.
