As I said earlier in the thread the installment system at Burnley is run by an outside source. I've been told that they pay the money up front to the club when they have a signed credit agreement although I can't vouch for that 100%. We have options to pay over 3 months or 10 months. To the club it's a no brainer, it doesn't cost them anything and they make season tickets accessible to a lot more people.
One other option we have is that the club sell vouchers in the club shop. These vouchers are not for general use but can only be put towards a season ticket. Another system to allow people to pay weekly. yes there is an extra element of admin but you can't have Lee sat their doing nowt all day
