Package tickets/deals i think is a great idea. Buy 3-4 tickets and get x% off. Those fans which buy 3-4 tickets anyway might get a nice deal. For others it might make them drag a friend or family member along to get the discount. That would be someone who would not have normally been there without it.
Or maybe buy 3 home game tickets in a row and get a reduced price. Keeps fans coming and locks them in to the next 3 games.
I don't go as much as i used to nor as much as I'd like. Simple case of not being able to afford - When i look at the day as a whole, I'm going to end up spending £60 on trains, buses, ticket, pie/beer/coffee.
