This seller :
has sold me a MAK code for Windows 10 Pro… These codes are not for consumers, only government, educational and corporate environments for large number of computers and activated over a KMS server. These codes are sold to more than one person and its possible that the person its sold too will find out its number of activations and then sell them on again… The risk involved means that once it reaches its maximum of activations and the buyer complains to microsoft, they will find out its a MAK code that shouldn`t have been sold to a consumer and it will get blocked.
This is bad for gameflip, and bad for the customers who have bought them.
