Ready to kick off the new year with some serious rewards? There's a flurry of limited-time offers you should know about. If you hold a Chase Sapphire Reserve, it's worth calling to see if you're eligible for a $400 retention offer. This is basically free money to keep a card you likely already find valuable! Several banks and credit unions are offering tempting signup bonuses for new checking accounts, like BCU Credit Union's $150 bonus. Crypto enthusiasts can snag up to $400 by joining OKX.

Beyond these big hitters, there are smaller, but still valuable deals available. Amazon is offering $15 off a $15.01+ purchase when you add an American Express card to your account. Rakuten has upped its referral bonus to a sweet $50. And, if you're a T-Mobile or Verizon customer, keep an eye out for a Chase Offer that could get you $50 back on a $50+ spend. Be sure to check the expiration dates, as some of the offers may have already passed!
