If you drool all over yourself when thinking about the deals you'll score this coming Cyber Monday, Citi has yet another deal for you to help kick off the holiday shopping season. $200 cash back, in the form of a statement credit, for spending just $500 online within the first 3 months on the new Citi Diamond Preferred Card. That's a 40% return on your initial $500 spend, which is an awesome deal for a no annual fee credit card. Most other card offers will require at least a $1,000 spend during the first 3 months to qualify for signup bonuses, so this is especially great if you plan to spend less this year on your shopping but still want to enjoy an attractive cash back bonus. While it's not entirely clear how purchases will be categorized as online or not, any shopping you do on sites like Amazon or Etsy should obviously count as online purchases. However, If you do purchase something from a store that has brick-and-mortar locations as well, I would make sure you check your statements closely to verify that all the transactions are properly categorized as "online" purchases. There are bound to be mistakes.
