Don't think the fans HAVE been fleeced but a hefty hike in ST prices would be harsh.Increasing the attendance figures for ALL home matches and not just the big games should be the aim. A competitively priced season book would do that.
In business it's all about getting your customer to trade up. The 'armchair' fan to take in one or two games, the 'half dozen game a season' fan to take up a ST, a ST holder to take a premier seat/hospitality package and so forth.....
