I've been saying for years that the pricing should be reduced - not sure how much is dictated to them by FTECB though.
Personally I'd like to see BOGOF offers on Championship games, for example. Maybe even something like £5 after Tea but that entitles you to come in after Tea on all four days.
For me it's all about getting people in the ground. Once they're in, they might spend a few quid on food and drink, in the long run they'll be more than likely to buy merchandise or to pay full price for other games of cricket - if people feel like they're getting a good deal, they're more likely to put more money into it.
I'd even offer travelling fans more of an incentive to come to games. Perhaps offer a deal where you can pay £25/30 and get every day of cricket your team plays at Durham - so potentially 6 days of cricket.
I'd also look at offering members deals on food and drink in the lounge. Maybe give them 3/4 tokens for a free Lunch. Which they could use whenever they want through the season.
I appreciate it's a lot to give away overall, but if people weren't going to come anyway and you can get them to come for nowt or for less than full price, they'll be more inclined to spend when they're in. I think it would be a great move to show that goodwill to folk.
