Better would be something along the lines of "You were only so good this year, and the time is up. If you want to talk more, you need to earn more good points with your mom and dad!"

No idea how you'd monetize that, though.

With 'in-app' purchases of course: 100 brownie points now only $10, hurry this offer won't last.

Somehow this device fits well with the Don't be a sucker video linked to elsewhere on this here site [1]. Good advice, valid in many contexts. Don't.

"Ho ho ho! I'm sorry but our time is up. If you want to keep talking to Santa, go into Daddy's wallet or Mommy's purse and bring Santa the rectangular cards with the numbers on it. Now, let's play a numbers game! You read the numbers on that card to me, and I'll tell you what you're getting for Christmas!"
