Most of our advertisers have a credit card or PayPal account on file and are charged automatically whenever the account balance is low. When you sign up, your credit card or PayPal account is charged a deposit amount of your choosing (as little as $30) in order to activate your ad and pay for your initial click charges. Then, whenever your account balance is low, your credit card or PayPal account is charged again to replenish your balance. The amount you’re charged is either three times your account daily spending limit or the sum of your last three days worth of click charges, whichever is lower.
If however, you consistently spend at least $10,000 each month on your account, you may be eligible for invoice payment.
