Great question!
The reason we ask for your credit card details is to ensure that any difference in cost is covered as the voucher value may not cover the exact dollar value of the bag chosen, or you may change your mind and swap your box type, or alternatively you can redeem the voucher and then let it sit there on your account until a later date.
At the moment, we are unable to have 'one-off' deliveries as an option to select from when you sign up with a voucher, but you do have the ability to select weekly or fortnightly when placing an order, can skip deliveries or cancel your subscription.
Credit card details are all hidden securely and are saved in our system should you decide to order another bag in future. Please note that the $1 is just an authorisation fee to test the card and it's reimbursed immediately.
