Citi Bonus Cash Center

Citibank divides its shopping portal into two camps: the Citi Bonus Cash Center and the Citi ThankYou Bonus Center. If you have a Citi card that earns cash back, such as the Dividend Platinum, then the Bonus Cash Center is yours to use. The shopping portal teams up with over 500 online retailers to offer you a cash back rebate, usually offered as a percentage of your purchase, as a reward for shopping.

The Bonus Cash Center goes even further, too, by offering in-store discounts and gift card deals. But don't get fooled by the online mall's supposed average 5% cash back. We calculated the average rate at 40 popular stores, and the Citi Bonus Cash Center returned an average of closer to 3% cash back.
