Just FYI for those of you who want to try for a lower apr, I just got 6.9% on my Amex Blue. I was at 10.9%, and they didn't want to budge for the longest time, so I was really suprised today.
Sorry for the delay in the response - its been pretty busy around here. Anyway, I had called the regular Blue number thats on the back of the card, and pressed 0, and asked the rep for a cl increase. When he told me that there had been an increase less than six months ago, I asked about the apr. Whats weird is he asked me why I wanted it. I told him that I used another credit card that had 5.9% (not exactly true), but I wanted to use my Amex regularly, and didn't b/c of the apr. Then he offered me the 6.9. My scores have hust recently gone over 700 (between 700 and 720).
