The deal, answered
Who can get the deal?

How much do I pay?
$23.20 per seat per month for your first 3 monthly invoices, then the normal $29. The discount is applied at checkout, so there's no code to type.
Does it cover more than one seat?
Yes. Every seat on your subscription is 20% off for the first 3 months, including seats you add during those months. People who only need to read your threat models don't need a seat at all: each paid seat comes with 3 free viewers.
Can I cancel?
Yes, at any time from Settings → Membership & Billing → Manage billing. If you go back to the Free plan, your forests aren't deleted.
What if I miss it?
