The case
What it does well, and what it costs you
Why it earns its score
- 5% cash back on gas and groceries for the first 6 months (up to $500/month)
- No annual fee, and accepted anywhere Mastercard is (including Costco)
- Cash back redeemable as a statement credit, deposit, or charity donation
Where it loses points
- The 2% gas/grocery rate is capped at $500/month combined, then 0.5%
- Weak 0.5% base rate on everything else
- The 5% rate is only an intro; it drops to 2% after 6 months

- No published income minimum.
- Practical constraint: The 2% gas/grocery rate is capped at $500/month combined, then 0.5%
Strategic fit4.5/10

- Main conflict: You spend more than $500/month on gas and groceries, or you want a strong base rate on other purchases.
