American ADHD'ers: settle a bet: how cheap+available (uninsured) is dextroamphetamine SR or ER/XR single ingredient?

I obliquely was referring to how insanely priced Dexedrine Spansules are in America and they countered with (unknowingly) that generics are almost always available for basically every med in America. Which, they're not outrageously (seemingly) totally out there but I dont think it totally captures how fucked US prices are for even the staples sometimes
