I bought gas. Why is there a debit card hold on my account?

If you use your PIN number when you purchase gas there may be a hold placed by the gas station that will stay on your account for (3) business days. The most common amount is $75, but it could be higher depending on the gas station. The reason is that when you use a PIN to purchase gas the gas station is not guaranteed to get their money, so they will preauthorize the amount where the pump will automatically stop. To keep this practice from happening just always use your card as a credit at the pump. It will still clear from your account but the gas station will not preauthorize the transaction for the large amounts like they do with the PIN transaction.
