There is an option to get CC for free. (I'll buy it ... but I don't know when)
It's called 'TrialPay'. As far as I understand this, you need to buy something from this website in order to get the game Cortex Command for free?

I mean, when you need to buy something from their site, you need to spend money. Why not buy CC from the beginning directly from the Data Realms site? Sorry, but I don't understand this ...

If you don't like it, don't use it. If you spend enough time looking, there are offers that do not cost money.

Wait what? Are you telling you can go and grab yourself a free CC key using trial pay and not pay anything for the offer (if its 0$ cost) they give you there?

I've browsed through them. There are options that are a) cheaper than retail and b) free offers (ie: free trial subscriptions that stay free as long as you cancel them).
