Before: what you give it
The example input, as typed in. You paste text, CSS, markup or notes.
heading: Go Premium button: Start my free trial link: No thanks, I don't like saving money text: Free trial, then $79.99/yr billed annually. Auto-renews unless cancelled. text: Only 2 left in stock! Offer ends in 09:59:59 checkbox: [x] Send me partner offers and share my details with third parties text: To cancel, call customer support during business hours. text: 1,200 people bought this today signup: 2 steps cancel: 6 steps
