Hey awardtrail fans! Rakuten's running a promotion where you can snag some extra cashback (or Membership Rewards points, if you're in that ecosystem) when you apply for certain Chase cards through their site. We're talking the Chase Freedom Unlimited, Chase Sapphire Preferred, and Chase Ink Unlimited. The bonus ranges from $25 to $50, but it all depends on whether you're already a Chase customer.

Here's the catch: the Freedom Unlimited and Sapphire Preferred offer a higher $50 bonus for new Chase customers, while existing customers only get $25. Strangely, the Ink Unlimited card just gives a flat $25, regardless of your Chase history. This is important because Chase has started cracking down on referral bonuses for business cards if the person signing up is already a Chase business customer. The takeaway? If you're eyeing the Ink Unlimited and already have a Chase business card, Rakuten's $25 might be your best bet since referrals probably won't work.

So, should you jump on this? If you're new to Chase and have been considering the Freedom Unlimited or Sapphire Preferred, the extra $50 from Rakuten sweetens the deal. Existing Chase customers might still find the $25 appealing, especially if you're big on Rakuten points. Just remember to compare it with other offers (like referral bonuses!) to make sure you're getting the most bang for your buck. Happy travels (and happy earning!).
