There is a GSF and GMS number that can be generated depending on which category you fall under. The dealer is probably trying to get the bigger discount for you but that is not always available. I thought the family was better than the friends one and you should be able to get the GMS number from your aunt (according to the details posted above). If you give your aunt your birthday, zipcode, and confirm that you do not work for the government, she can get you the discount code in a few min. It should be a series of letters & numbers with a dash and then the GMS at the end since nephew falls under the family group there. That number is all the dealer needs.
