You are not charged for your Fetch vehicle until the day of your rental.
When you start your rental, Fetch will charge the amount for your scheduled rental to the credit card you have on file.
Additionally, a $150 security hold will be placed on your card. This security hold is automatically refunded when you return your vehicle without any damage or problems.
If you exceed the included miles with your rental, you'll be charged for the additional usage at the conclusion of your rental.
