Been using this site for over two years and have only had great experiences. They offer product keys very cheap. I personally pay through PayPal so my card info is not on the site, but have never had any fraudulent transactions. After purchasing, keys always show in your inventory on the site. I usually check out the vendor before purchasing any key, but have yet to receive a fake or used product key. Kinguin also sent me an email with a ‘Gaming Police’-bit which gave me a chuckle.
