Pricing
Most of this site is free. What follows is a complete list — nothing left out, nothing invented. Every dollar figure below is quoted from the same file the checkout code reads it from, cited inline, so this page can never drift from what you're actually charged. For the mechanics of each product, see the playbook store and the FAQ.

Every account described above is simulated: paper money on real market prices, except the separately disclosed real-money test at /real.html. Nothing on this page is financial, investment, legal, or tax advice, and no price here changes what the checkout page actually charges — Stripe's own checkout is the final word if the two ever disagree.
