After checking out another thread about waiving the $18 dollar upgrade fee. I'm wondering if any of you have any tips on getting At&t to waive the $36 dollar fee for adding a line to an account. My parent's account has been around since 2007 and I previously had an account with them since 1999. I moved to Sprint in 2008 to get a SERO account which I've since given to my wife. I will be porting my number over from Sprint and paying a $60 ETF to get back onto At&t so saving $36 would be great. I'm moving over to my parent's plan to save some money to begin with... Much thanks for any tips.
