Card payments are not open yetThese are the prices. Payments are still being set up, so choosing a plan today tells you to come back rather than taking your money. When they open, the amount charged will be the amount shown here, read from the payment provider rather than typed in by us.

BEEP / THE MYTH-BUSTER
The free plan is not a trial with the good bits removed. It is the part of this site that explains things, and that part was never the thing to charge for.
Things worth knowing before you pay anybody
- A failed payment does not lock you out on the day. You keep the plan until the period you already paid for ends.
- Cancelling stops the next charge and leaves everything working until that period ends. There is no exit fee and nothing to ring up about.
- An allowance that runs out is a wait, not a wall. It starts again next period, and the free parts of the site never stop.
- You can see exactly what you have used, and when the next payment is due, on your account.
