Personally all my PC builds for the last decade have been Enterprise keys issued to me from my work, and I've always activated them the normal way. I sometimes see those deals on tech websites for super cheap keys, usually less than $15. Always was curious if those would work just fine, but never had the opportunity to try them.
I've bought a few $10-15 keys that work perfectly fine. Never through ebay though.
