2024: where to buy 18650 LiFePO4 batteries?

Two of the eight cells in my Reform suddenly discharged to 0.0V and my attempts to revive them with a benchtop power supply were unsuccessful. (One wouldn’t charge past 1.24V and wouldn’t hold it; the other wouldn’t charge at all and drew zero amps)

Does anyone have a reputable source for LiFePO4 cells that will ship to the US? The previous threads about this topic are from 2022. Is Eremit still the best source? I can’t tell if they ship to the US.

I’ve done fine just ordering from vendors on AliExpress so far. I haven’t taken note of which ones.
