I preferably want to use a site that has a reputable payment processor such as PayPal. I've lost about $30 in total by trying to by windows product keys from users on certain subreddits but they've never ended up sending me my key. I want to use a windows key site that is trustworthy. I don't want to get one on reddit because I've been left empty handed by some people who sell on a sub reddit before. I was wondering on where to get a legit windows 10 key.
