Can I just get the version without CoPilot for cheaper? Or at all?

Likely they'd charge more for it.

I think the only way to get the no-Copilot version now is to already have the Copilot version and try to cancel your subscription, and only then they'll offer the "Classic" version sans Copilot as a last ditch retention effort. If users actually wanted this stuff they wouldn't need to bury the option to not pay for it.
