Update: This offer is no longer available.
I reviewed the Citi Diamond Preferred Card last week because they're running a special holiday promotion that offers $200 cash back after you spend $500 online during the first 3 months. While this a great sign-up bonus, I personally wouldn't use the card for anything more than scoring a free $200 on Cyber Monday. Beyond the $200 cash back, it doesn't offer any rewards program and is really more of a balance transfer credit card due to its long 0% interest period. Since I never carry credit card balances and am a self-professed rewards junkie, that makes the card pretty much worthless to me in the long run. Many of you may feel the same.
