Check out this blog post made by a clickbank affiliate.
"ClickBank will withhold the first check to be issued from your account until the payable balance contains sales made with 5 or more different credit card numbers, including at least one Visa card, and one MasterCard in order to be eligible to receive a check."
"Accounts with a positive balance but no earnings for an extended period of time are considered dormant. Dormant accounts are subject to a charge of $1 per pay period after 90 days of inactivity, $5 per pay period after 180 days of inactivity, and $15 per pay period after 365 days of inactivity."
I never knew about the clickbank policies.
