On the same subject as the pledge that my lil bro was on about, what about this for an idea.
If you are associated with an amateur rugby league/union club you get a south stand season ticket for £70 until the end of November. Each club could get their numbers and then order their tickets and this may help to get new and old supporters through the turnstyles.
I haven't had a season ticket for the last couple of years as from a financial point of view, there is no point. I generally miss a few games because of holidays/prior commitments so I would end up being worse off having one.
If the club are to go down the pledge route, maybe 3000 tickets sold would end up with £75 tickets. Therefore, this gives a discount to those who are associated with an amateur team, hopefully helping to boost the game at that level too.
