While there is no cost to join TruckersB2B, we do charge a $12 check processing fee when an actual rebate check is issued to help cover the cost of processing your information and mailing your rebate check. This fee is deducted from your total rebate amount, it is not cumulative, and you will never owe TruckersB2B anything. If the check processing fee is larger than your actual rebate, you simply will not receive a rebate that month. If you do not receive a rebate in a given month, you are not charged anything.
