In Germany you just purchase an OEM volume license on eBay for 8€
[X]Doubt
Having purchased $8 keys on eBay, they're more than likely either data center or MAK activation keys that are being resold against the license agreement.
Not that I care, mind, but there's very little likelihood that a real/legit key being sold for that little that's actually OEM.
Edit: IMHO, there isn't much difference in buying a grey market key vs just using the activation script.
This is my problem, I've been plagued with the curse of competence and an inability to keep my mouth shut. This leads me to accidentally volunteer for seemingly easy tasks that 'only require a bit of automation.....' and I lose weeks of time.
