Yes, you can. I have a credit card from citi. I have been getting cash(they send check). If you have citi credit card, log on your account. On the right side, you can see the icon "  Earned dollars". If your accumulation is more than $50, you can request a check for you, either by calling them or online. If you want to do online, just click on "see details" right below your accumulated dollars. After you click it, you can see your rewards detail. If you go almost to the end of that detail ( on the same page), you can see an icon, "Request Rebate Check". Click on it and do whatever you are asked to do. After a few weeks(Maximum 2 weeks) you will be able to get your check in your mail box.

Cheers!!!!!!!!!!
