A $0 trial only runs a weak card authorization, so invalid cards slip through and only fail once the real charge fires days later. Applying a $11-off, duration=once Stripe coupon at checkout charges $1 for real on the first invoice instead, which validates the card immediately, then reverts to the full monthly price on the next invoice with no manual swap needed. |
