Maybe maxrewards could contact cashbackmonitor.com for an integration. I'm not sure if that site is kept up-to-date, but it's a shopping portal aggregator

I’m wondering if the technology to include the portal info isn’t available yet, if that’s true, maybe they could include a visual way to note that a card has a shopping and dining portal?

Or there could be a category for Restaurant - Portal that would only include cards that have dining portals for example? So that it would at least be easier to keep track of.

It would be really helpful if the credit card / portal providers would provide their database info on what’s in the portals to apps like this so that people wouldn’t have to go looking at each portal to find the best deal. I’m just skeptical that they will b/c they want us to have to go spend time looking at their portal.
