For every season ticket you purchased, you were given a voucher for a free pre season ticket. Let's say they sold 13,000 season tickets. That means that they could have given away up to 13,000 free pre season tickets. It also wasn't a sell out, there was at most 25,000 that showed up to the pre season game.
They might give away some tickets to the regular season game, but It'd be less than 500 would be freebies, if any.
It was smart to give away tickets to the pre season game though, make some concession and beer money on people that would otherwise stay home.
And yes im going, gone to almost every game since I was 5 years old, drove down for every game the past 2 years in Saskatoon but ive moved back to Regina. Even went up for the West semi final in Calgary last year, amazing experience!
