What is a 'proper' price to pay for a Windows 10 Pro product key? This site <removed> which appears legit has it for $80, whereas the Microsoft Store wants $419.
For context, I was doing a clean install of a 10 Home machine and accidentally installed Pro. Going back from Pro to Home seems to be a bit of a mission and I rather like Pro, but I'm not planning to shell out $400+ right now!
