I was reading a thread about opting out and remember that I did that not to long ago. Could that be one of the reasons citibank offered me that generous credit limit? Since I did not get a instant approval, maybe the person evaluating my application was thinking: "Hey this person opted out , so less chance for him accepting any promotions , so less chance for additional debt." what do you think?
Citi is crazy!! Gotta love 'em. The person who reviews the apps was probably laid off - computer set to accept all, hehe.
