15. I've made a sale, why haven't I received a check?
There are two possible reasons:
1. You may not have reached your selected payment preference, which is the minimum amount of money that must be in your account before we send you a check. In your account you may select an amount from $10 to $10,000 as your payment preference. The default setting is $100. We hold your check until your payable balance reaches this amount.
To change your payment preference, simply login to your account, click the "Account Settings" tab. Select the desired amount from the drop down menu for "Payment Threshold", and click the "Save Changes" button.
2. You may not have met the Customer Distribution Requirement:
ClickBank accounts cannot be used for the sole purpose of collecting rebates or otherwise extending credit to yourself or others. In compliance with US law, ClickBank will withhold payment of any account balance until it contains standing sales made with 5 or more different credit card numbers, including at least one Visa card, and one MasterCard. PayPal and eCheck purchases do not count toward the minimum.
