> Discover is accepted by, what, two retailers? Discover acceptance is near-universal (at least in the US) as of the late 2000s/early 2010s.

I've used a Discover card for 99.9% of purchases with extensive travel across the US for the past 15 years or so. Very occasionally a place won't accept it, but it's become a rather surprising thing to encounter.
