Its said because of "new federal regulation starting Oct. 1st"...
ha, well -- october 1st is when the durbin ammendment of the dodd-frank goes into effect so maybe there is some wording somewhere that would prohibit this. that their prepaid card even had allowed withdrawal of funds via ach transactions is something that wasn't widely known.
more likely is that banks and financial entities don't like getting their debit card fees regulated by the feds and are blaming that action for every change that will be seen negatively by their customers.
