140$ sounds like price for perpetual license that binds to your Microsoft account and can be transfered from pc to pc. But you can buy legit oem licenses that cost something like 40$. You simply won't be able to move it to new pc, but usually it doesn't matter much. People avoid them cause "surely if they are thus cheap they must be scam", but it's not. They simply have restriction of permanently binding to single hardware. But again, usually it's worth it anyway
