Citi card customers can earn extra cash-back rewards by shopping for gifts online through the Citi Bonus Cash Center, which features more than 400 stores and specialty retailers. Customers earn an average of 5 percent cash back when shopping through Citi Bonus Cash Center, according to the Citibank website.
Consumers who specifically have a Citi Dividend card might want to enroll their card for this quarter's bonus rewards offer. They can earn 5 percent cash back on department, clothing, electronic and toy store purchases through Dec. 31 and 1 percent cash back on all other purchases made with the card.
