Up to $150 with the MBNA Smart Cash Credit Card!

Q: How do I earn the $150 cash back on the MBNA Smart Cash Platinum Plus Mastercard?

The current promotion on the MBNA Smart Cash Platinum Plus® Mastercard® grants 5% cash back on gas and grocery purchases for the first 6 months, capped at $500 in monthly purchases per category. At maximum participation, that equals $25 per month for 6 months = $150 in cash back. After the introductory period, the rate drops to the regular 2% on those categories. The card has no annual fee, so the welcome cash back is pure upside on top of the regular earn structure.

Q: What are the ongoing cash back rates after the introductory period?

Once the 6-month welcome period ends, the MBNA Smart Cash Platinum Plus® Mastercard® earns:- 2% cash back on gas station purchases (up to $500/month spend, then 0.5%); - 2% cash back on grocery store purchases (up to $500/month spend, then 0.5%); - 0.5% cash back on all other purchases, including Costco; The $500 monthly cap on each category means a maximum of $240 per year at the 2% rate, beyond which all spend defaults to 0.5%. This makes the card best as a complement, not a primary, for households with above-average gas/grocery budgets.

Q: Is the MBNA Smart Cash Platinum Plus Mastercard accepted at Costco?

Yes. The MBNA Smart Cash Platinum Plus® Mastercard® is a Mastercard, which is the network currently accepted at Costco Canada warehouses (Visa is not). However, Costco purchases earn the base 0.5% cash back rate — not the elevated 2% grocery rate — because Costco is classified as a warehouse club, not a grocery store. If your household does most of its grocery shopping at Costco, this is the wrong card to maximize that spend; pair it with a card that offers a better warehouse-club return.
