FYI, the local branch banker who signed me up for Citigold called me today and said she still didn't have the definitive info re: the prestige $100 fee discount for Citi Priority.
She also mentioned that since I signed up for Citigold very recently, in mid-september, my account might not get converted to Citi Priority on November 6, and I should get at least one year of Citigold before the conversion to Priority.
