I recieved my Amex Blue with a $3000.00 CL. YIPPEE!! I also recieved a separate letter stating my Experian Score was 753. Do they use the same scale that Equifax use? I know some folks talking about vantage scale, where the score can range from 300 to 900 or something like that... I am trying to find out if my score is 753 with EX will my EQ score be just as high or ball park?
