Rakuten, the online shopping portal that gives you cashback (or Amex points!), is running a fantastic referral bonus. If you sign up through a referral link and spend $50 within 90 days, you'll get a cool $50 bonus. Even better, the person who referred you gets $50 too! This offer has been extended and is valid through March 31, 2026, so you have some time to take advantage. Why should you care? Well, $50 is basically free money for doing your regular online shopping! To make it even easier, you can just buy a $50 gift card through Rakuten at places like Visa, Starbucks, or Home Depot to trigger the bonus. Think of it as a way to boost your travel fund with minimal effort. Plus, you can refer your family and friends and rake in even more rewards. Don't forget that you can also opt to earn Amex Membership Rewards points instead of cashback through Rakuten, which can be super valuable for booking those dream trips!
