Congratulations. That is Navy's best card for BT, 0% APR over 12 months, and low APR for purchases. Navy Full Speed Ahead!!!! I usually advise others to go for the 91/3, but in your case, I will say wait until another serious situation comes up for your 2nd card. Milk the 1st card 0% APR for what it's worth.
