Stack Your American Express Card’s Credits With Increased Cash Back Rates

I like to use Cashback Monitor to find and compare the best shopping portal rates. If you’re not familiar with it, this guide can show you how to use Cashback Monitor to always get the best deal.

These are the best rates available right now, but I expect them to only be valid for today (July 15th).

The Amex Platinum card comes with a semiannual credit of up to $50 at Saks Fifth Avenue (up to $100 statement credit per calendar year; enrollment required). I used this credit today and stacked it with 14% cash back at Saks Fifth Avenue with Rakuten (Ebates). On top of that, I was also able to take advantage of free 2-day shipping thanks to my Amex card’s free Shoprunner membership and I got an additional 10% off because it was my first online Saks Fifth Ave. order (and I signed-up for the Saks email list). Overall, I placed an ~$83 order that will only end up costing me ~$7 out of pocket—That’s a savings of 91%.

You also could use your Amex Business Platinum card’s semiannual Dell credit of up to $100 (on purchases in the US; up to $200 credit per calendar year; enrollment required) and earn 15% cash back at Dell through TopCashback.

The Amex Gold card has a monthly up to $10 dining credit, which is valid at Boxed (enrollment required; up to $120 per calendar year). Right now you can get 10% cash back on Boxed purchases through Rakuten (Ebates). It might not be that much savings on a $10 purchase, but something is better than nothing.
