After searching around here, I have not yet see a discussion about the Amex Corporate Advantage program (
https://www.americanexpress.com/us/credit-cards/gcpadvantage/login/). It offers great annual statement credits (i.e. every year!) to offset the annual fee for many cards. For example, my offer includes:
Amex Plat:
$150 annual statement credit
Amex Gold:
$100 annual statement credit
Amex Green:
$75 annual statement credit
Blue Cash Preferred:
$50 Annual statement credit (effective $45 AF!!)
Some notes: If you already have some/all of the cards included, you CAN still get a statement credit (call/chat). Furthermore, if the signup bonus or min. spend is worse via the Amex Corp Advantage site, you can still apply using a better link, then chat them to get the statement credit (for example, my offer of the BC Preferred was $3000 min spend, whereas it's normally just $1000, so I applied elsewhere to get just $1k min spend).
Again, the link to check you Corp card:
