In Recommended sport centers you could find verified sport centers by VAŠE LIGA players. There you could use a discount. When booking a court just say that you are from VAŠE LIGA. Then tell it to the receptionist when you arrive and they will check if you are on our list. Be sure to ask for your discount when you arrive. Sometimes it might not be possible after the match.
In Other sport centers there are other options for you to play the games. Sometimes you could also use a discount there. Don't you see your favourite sport center? Contact the administrator in your city. He could add it.
