I made purchases with CJS CD Keys and was very happy with the results. On one occasion though, things didn´t turn out well. But, it was the fault of one of the providers to the platform, not the platform itself. They ended up giving me a refund (although, a refund for doing future purchases in their platform, which is OK). They were kind, understanding and replied very timely. I can certainly recommend them. One suggestion though: If you buy an account for a program/game/etc. where you´re given a username and password, try to change the password as soon as you can as an added safety measure.
