The voting by mail option cost Massachusetts eight-million-dollars for last month's election. 

Secretary of State Bill Galvin says just under half of the three and a half million people who voted cast their ballot in person on Election Day.  The rest voted by mail or took advantage of early voting options. 

Around four-million-dollars was spent on incoming and outgoing postage for the mail in ballots, with nearly a million-dollars more spent to print the ballots.
