I always wondered how the gas pumps knew if I had enough money for the gas I was about to take. Today I found out because this morning, I attempted to renew my subscription to Everquest 2, and my transaction was denied. Having a much larger available balance on my credit card, I became quite worried as to why it wouldn’t approve. After placing a call to customer service, my creditor explained to me that the merchant had made the error and never asked for funds, so all is well with my credit account. Phew.
He then wanted to confirm the available balance I saw with the one he saw and all was well except for one thing. He asked, “Did you purchase gas from the pump on Tuesday?”
“Yes, sure did, about ten dollars worth. Is there a problem?” I replied.
He went on to explain that everything was fine, and that I should adjust my balance because when you purchase gasoline from the pump, the machine validates that your credit card has at least one dollar of credit, no more. This is immediately posted away from your available balance, but the actual amount of money spent isn’t requested from your creditor until after a few days. So, you actually pay $1 to pump the gas, and pay the rest later. Go fig.
