Why it earns its score

- 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

- Weak 0.5% base rate on everything else
- The 5% rate is only an intro — it drops to 2% after 6 months

Households with steady gas and grocery spend who want a no-fee card and a strong 6-month intro rate.
Who should skip it
You spend more than $500/month on gas and groceries, or you want a strong base rate on other purchases.
