I want to say that's a relatively recent change.

Yes, sometime within the last 5 years they broke their long partnership with AMEX. It seems to be Citibank now.

Have to wonder whether it’ll change in another 5 years.

Making 4% back on gas is mega killer though.

My understanding is that they changed because Citi offered them a better deal.[0]

That said, I do kinda miss the Amex and its automatic extended warranty.

The Costco Visa also include an automatic warranty extension of 2 years beyond manufacturer.
