Debit cards are different ! Its like writing a check , they want to make sure that you have money in the bank , ain't nuttin wrong with that ! Think about it from their view , if you pump and then your card bounces , what then . Use your credit card , they should know immediately if your credit is good ! A credit card is better for for you in a dispute , you can call the card company and they will stop payment on that credit transaction , not available on debit card , its to late the money is already gone !
