Heads up, awardtrail readers! Rakuten's offering a sweet deal: 10% cash back or 10x Rakuten points on StubHub purchases today only. This is great news if you were already planning on buying tickets, but it’s especially clutch for Chase Sapphire Reserve cardholders.

Why? Remember that $150 annual travel credit? Many people use StubHub to burn through the second half of that credit each year. This Rakuten deal lets you double-dip: use your CSR credit AND get 10% back from Rakuten, essentially getting extra free money! Even if you weren’t planning to buy event tickets, you could buy something small on StubHub just to trigger the credit and pocket the Rakuten cash back (or points!). It's like getting paid a little bit to use a benefit you already have.

Finally, if you're new to the Rakuten game, now's the perfect time to sign up. They're offering a $50 or 5,000-point welcome bonus for new members. Free money and miles? Yes, please! Just remember to check the portal rates on Cash Back Monitor to make sure Rakuten is still the highest!
