A loyal reader of monitorbankrates.com alerted us to this deal. Citibank is offering a $100 checking account bonus for AT&T Universal Credit Card holders who currently don’t have a checking account with Citibank.

To receive the $100 checking bonus, you have to open a Citibank regular checking account and “perform qualifying activities.” When you open a checking account you have to make a minimum deposit of $1,000 by January 31, 2010. 

The “qualifying activities” include one direct deposit into your checking account or two electronic bill payments or at least five “qualifying signature debit card purchases” for three consecutive months. Check on interest checking accounts.

The offer comes with your AT&T Universal Card statement. You can sign up for the $100 checking bonus at any Citibank branch, online at offer.citibank.com or by calling 1-866-524-8635. The offer code our reader was given is C2X5. You can try this code or ask Citibank for one, I don’t see why they wouldn’t give you one if you have an AT&T Universal Credit Card.
