What exactly do you want to know? Unfortunately, your question is completely incomprehensible: /

Whether the game costs cheaper than a normal cd game that is my question whether it costs 10/20 euro

Usually you should be able to pay with PayPal. Games on MMOGA, Instant Gaming, etc. Are often a little cheaper. But you're talking about PS4 all the time. But you have selected the game as a PC version.
