Here they have these same parties organised by cigaret companies but it's illegal for people to go to parties like that which are associated with cigarets...so what these companies do is they send sms's to these people like: You wanna party? Go to this postoffice ask for a package for Mr. Somebody and your invitation will be in there, then you have to send a reply sms with some code on it. Nobody knows where these parties will be until the last minute...
