    Common questions

    Which card has the bigger sign-up bonus, Chase Ink Business Unlimited or Citi Diamond Preferred Card?
    The Chase Ink Business Unlimited has a public bonus ($750 bonus cash back, worth roughly $750), while the Citi Diamond Preferred Card doesn't advertise one right now.
    Is the Chase Ink Business Unlimited's $0 annual fee worth it compared to the Citi Diamond Preferred Card?
    The Chase Ink Business Unlimited has no annual fee, so the question is whether the Citi Diamond Preferred Card's $0 fee is justified by its perks. If you'll use enough of the Citi Diamond Preferred Card's benefits to clear $0 in value annually, it's worth it; otherwise stick with the Chase Ink Business Unlimited.
    Can I have both the Chase Ink Business Unlimited and Citi Diamond Preferred Card?
    Yes, since they're from different issuers (Chase and Citi) the application rules don't conflict. Many points enthusiasts hold both, they pair well when one earns flexible bank points and the other earns a different currency.
    Should I get the Chase Ink Business Unlimited or the Citi Diamond Preferred Card first?
    Get the one whose sign-up bonus you can hit comfortably without overspending. Chase Ink Business Unlimited: $6,000 spend in 3 months. Citi Diamond Preferred Card: no published min spend. Pick the easier minimum spend if you're new to points; pick the larger bonus if you have planned big purchases coming up.
