Question Can I buy win10 from this site?

[daxmashburn]

I saw a 14 dollar windows 10 key on g2deal.co
Is this site legit? Would it be safe to give to best buy to put on my new mobo?

Chances are the key is either stolen, or invalid.
Grey market keys like that may work for some time, until MS decided to go around and clean out keys that should no longer be in use.

Either pay for a legit key from MS, or use windows unactivated (free and legal, just some personalization options gone)
