Thing is over the years we had seasons we tried super cheap season tickets like other clubs are now, in the hope we would sell a lot more at the cheaper price and it didn't work well enough to justify continuing to do it.
We literally offered free tickets against Sunderland and still couldn't get a sell out.
The attendance issue has never been caused by prices it's a lack of interest. I think you could let every game be free admissions and we probably wouldn't see a massive increase in home attendances.
There are lot's of potential reasons why we have so few fans: the proximity to 4 massive clubs in City, United, Liverpool and Everton plus so many other clubs in north west meaning our catchment area is very limited and glory hunters are spoiled for local choice. The bitter rugby rivalry splitting the town's support and maybe even some folks from St Helens, Warrington, Widnes etc not wanting to support a Wigan club even in football due to the rugby rivalry.
Not just that but the majority of other clubs on our doorstep have been around a lot longer than us, especially as league clubs so have so many more generations of fans growing the fan base compared to us. Which is why I think targeting the young football fans in Wigan and the surrounding areas who aren't Latics fans is our best way to go.
I would also target trying to dissolve the hatred with Warrior's, some folks won't want to let it go and it will take time but you've got to start somewhere as their fan base is potentially a largely untapped market who may not feel welcome attending Latics games.
