Reward Maximizer

Stop leaving money on the table. If you have credit card offers sitting in multiple bank portals, you're probably missing the best deal every time you shop. Reward Maximizer fixes that.
The Problem
Every major credit card has portal offers — Amex might give you 10% back at Nike while Chase gives you $15 cash back. But checking each portal separately before every purchase? Nobody does that. So you use whatever card is in your wallet and miss out.
What Reward Maximizer Does
It syncs your offers from Amex and Chase into one dashboard. Visit your card portal, click sync, and you're done. Now when you browse Nike.com, a banner appears telling you exactly which card to use and how much you'll save — no guessing, no tab switching.
Stack for Even More
Here's what most people miss: you can combine a card portal offer with a cashback site like Rakuten. Reward Maximizer flags these stacking opportunities automatically. Use your Amex for 10% back AND go through Rakuten for another 8%. That's 18% back instead of 10%.
Real Dollar Comparisons
"5x points" sounds great, but is it better than "3% cash back"? Reward Maximizer converts everything to cents per dollar using customizable point valuations so you can compare apples to apples. It marks the best deal with a BEST badge — no mental math required.
