You will need to authorize your payment when you create your first campaign. We will not charge you until your campaign starts to run.
Once your campaign is running, we will pre-charge an ads payment based on your daily cap (normally 3 times your daily cap). The payment will be used for the advertising fee in the following days. When the payment is used up, a new payment will be charged.
The ads will be removed when the daily cost reaches your daily cap.
