A credit voucher is a pre-approved loan awarded to each club member at some point in their contract. It allows the selected person to use it to get a car from a dealership.
It's basically a gift card from savings.club that allows you to get your car!
You can pursue a car worth more or less than your voucher if you change your mind about the vehicle you want. The extra balance resulting in getting a car worth less is carried over to your club account. If you want a car that costs more than the voucher's value, you must provide the difference when you visit the dealership to claim your vehicle.
