Membership FAQ
Quick answers before you join
What is the birth-month subscription?
It's a recurring monthly plan for repeat Cosmic Slime families. You pay a flat rate each month and unlock perks across every booking — priority weekend slots, a free add-on during your child's birthday month, and a sibling discount on extra parties. Checkout is finalized by the owner after signup; recurring billing is handled manually to start.
How do the perks differ across tiers?
3-Month Starter gets you a single party package, priority weekend slots, one free birthday-month add-on, and 10% sibling discount. 6-Month Family adds early theme access, two party packages across the term, and a 15% sibling discount. 12-Month Cosmic unlocks unlimited priority weekend slots, a themed decor upgrade each birthday, a 20% sibling discount, and VIP loyalty perks like surprise add-ons and early theme previews. Checkout is finalized by the owner after signup.
Can I cancel anytime?
Yes. The subscription is month-to-month and you can cancel at any time before your next billing cycle. We confirm every renewal with the owner — there are no surprise auto-renewals. Checkout is finalized by the owner after signup, so cancellations are handled with a quick message rather than through a portal.
When does my billing start?
Billing starts the day you sign up and recurs monthly on the same date. Your perks are active from day one — including priority weekend slots and the sibling discount — so you can book your first party right after signup. Checkout is finalized by the owner after signup.
Is this a one-time purchase or recurring?
Recurring. You pay a flat monthly rate for the duration of your tier (3, 6, or 12 months) and the perks stack for the whole term. After signup the owner finalizes checkout and confirms the schedule with you directly — recurring billing is handled by the owner, not a third-party portal.
I'm a subscriber — how do I book my next member party?
Head to the member portal and enter the code from your welcome email. You'll see your tier and remaining party credits, plus a one-click "Book my next party" button that fills in your kid's name and applies your sibling discount at checkout.
