How are you supposed to use the service if you do not bank with one of the banks that obviously pays you money to be involved? Any other service that I have EVER entered my bank information into has allowed me to enter it manually, but AGAIN you don’t have that option because my bank, even though it is one if the largest banks used by Military personnel, won’t pay you to be part of your site. If you really CARED about your customers you would provide the option to enter you account credentials manually.
