I just got my interest lowered from 9.7 to 2.9 for 6 months on puchases. I just called the number on the back of card and asked since that was what new customers could get. I have had it two years so I told them I thought I should be able to get it. Wanted to let others know if that will help anyone.
My credit limit is 10,OOO. they have been good to me. Infact I had applied for a new card but got a letter that I could only have one card with them, so I thought that maybe they would allow a lower rate on the excisting card and they did.
