Cardholders who enroll in this quarter's bonus rewards offer can get 5% cash back on purchases at department stores, clothing stores, electronic stores and toy stores through Dec. 31 and 1% cash back on all other purchases. Those who spend $750 within the first three months of opening an account will get $150 cash back.
Shoppers can also earn extra cash back rewards by shopping for gifts through the Citi Bonus Cash Center, which has more than 400 retailer partners.
Read the fine print: There is no annual fee and an introductory offer of 0% APR for the first 15 months, but after that the variable rate jumps to 12.99% to 22.99%.
