My Discover It recently graduated, and I have not been able to get a CLI (maybe I should wait 91 days after graduation?). However, I thought I should really try for an APR reduction.
Tonight I got on chat and asked for an APR reduction and/or a CLI (I wasn't sure if they could put in for a cli for me).
APR reduction approved: "The interest rate of 23.24% variable APR can be reduced to 18.49%..." almost 5% lower, so I accepted that offer. I think I've only ever reported a balance on this card a few times, and never more than about $50.
CLI request: He gave me a link to the CLI request page... And of course it was denied. Oh well.
Win some, lose some, I guess.
