You pay for the people who actually show up. Nothing else.
Every plan loads claims each month and unlocks more of the platform. Run past your load and claims just bill at the rates further down. Nothing switches off.
* Rolling out during beta. Your plan includes it as soon as it reaches your account.
A claim is one person grabbing your drop. Your plan loads your first claims each month. Past that, they cost this, and the rate falls as you grow.
Rates are per claim, measured on your total claims for the month, and they reset each month. You are never billed for the gift itself: hand over a $12 sandwich and Yaystack charges you for the claim, not for the sandwich.
Two ways your reward reaches people who were not looking for you.

Yaystack runs the chests: augmented reality loot boxes players hunt down and open for one prize out of many. You offer up a reward, we choose where it lands, whether that is a chest, an event or a show. Nothing for you to place or schedule.
YayListers are creators with followers who already trust them. Offer one of them your reward, and they drop it to their own audience in your area. Their followers show up at your door, and you still only pay per claim.
