Thats actually how Stripe works by default. They always show the actual amount that will be charged after the trial. So even though they are not going to be charged anything today, they like to be transparent and show the user what they are agreeing to pay (after the trial is finished). If you subscribe to the plan, you will see that it won’t charge you anything until the trial period is finished. We will investigate this more to see if Stripe offers an option to customize the amount text in their checkout popup window.
