When I wrote this in September 2026, I had just added Chase shopping portal rates to CBYS. Chase has one shopping portal, but weirdly, has two different sets of rates. One set of rates is available if you have a card in the Freedom family; the other set is available if you have a Sapphire card.
Curiously, the Freedom rates are typically ~50% higher than the Sapphire rates. If you have a card in both the Freedom & Sapphire family, you can access both rates - compare the actual rates before clicking through. The pattern I saw is a reason to check both, not a guarantee that Freedom always wins.
In other news - if you have some well-aged C1S accounts you haven’t used in a few months (who would ever have such a thing?!), try logging in and clicking around into merchants you’d actually shop at. This will likely trigger C1S to both 1) email you ‘email reactivation’ offers, and also 2) show you ‘web reactivation’ offers on the site and app. These reactivation offers are pretty nice - $50 off $100, $100 off $200, etc, for whatever stores you’ve been looking at. The T&Cs appear to allow for 1x email and 1x web reactivation offer per account. Not a bad perk for logging into an old C1S account.
