Pain at the gas pump goes beyond the high prices : Gas stations are also putting bigger holds of up to $175 on customers’ cards when they swipe. When drivers insert a credit or debit card at the pump, the gas station doesn’t know how much fuel they will buy and it places a hold on the account for an amount set by the gas station. Merchants authorize the payment networks to lift the hold once the final total of the payment is determined, though the holds can take hours and sometimes longer to settle—raising risks of overdraft penalties for debit-card users and eating into credit limits during the holds.
