text: buy the package with using a checking account?   i would never provide my routing number & checking account number in an electronic-check method.  mainly because, if the merchandise is not as expected, it's way harder to dispute the purchase.  i would rather use the debit/credit card that usually comes free with a checking account.  as a credit-based transaction, you have to your advantage the ability to file a dispute/fraud and get your money back (it's under visa/mastercard guidelines).  never ever give your routing & checking account number unless you *absolutely trust* the other party.
