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 an Insufficient Funds change. To avoid this situation, make automatic payments using something other than a Savings Account or MMA, such as 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 UFCU Bill Pay to automatically send payments to the merchant, rather than authorizing the merchant to automatically withdraw payments.
