Outside of my store cards, my lowest is BofA and Discover at 9.99% and highest is 15.24% for Chase.
Any idea how much AMEX would let you charge to your Plat?
Have you ever played with the check spending button? You should try $100k.
Wow 7.9% BofA? I thought 9.99% was great. And it allowed me $70k the last time I checked for fun. I didn't want to keep trying and get flagged.
