There is a sign up to register any FIA credit card (Bank of america or other
cards that are serviced by FIA like the Schwab or Fidelity cards etc.) The
offers range from statement credits after meeting a spending threshold to
bonus points for spending in certain categories etc.
You do not need an offer/registration code. Just click "don't have one" then
you can enter in the last 4 digits of your card number, last name and zip
code to get your offer.
