You guys are really nice! . I have been working on APR reductions for the last week and have my Amex Blue and FIA Fidelity Plat down to 9.99%. Chase would only reduce by 3% and told me to try again in six months. Some time ago CITI lowered mine by 2% on my Dividends card.
When I want a CLI or an APR reduction, I get down right pushy. These are some of my tactics:
1.) Demand they give me a CLI that matches my highest CL on my other CCs
2.) Demand they match my lowest APR on other cards
3.) Demand to talk with a real decision-maker, ya know move up the latter
4.) If I really don't need the CC, I threaten to close it and more often then not get sent to the retention dep't
YMMV with these tactics but I have had great success.
