Yes. These payments (which you might know as “ACH” or “EFT” transactions) follow Regulation D limitations. Any withdrawals attempted beyond your monthly limit will not be honored, and you will receive a notice by mail and incur a nonsufficient funds charge. To avoid this situation, make automatic payments using a checking account. Contact the merchant to arrange this change and be aware that your request could take more than a month to go into effect. Alternatively, consider using Bill Payment in Online Banking to automatically send payments to the merchant, rather than authorizing the merchant to automatically withdraw payments.
