Didn't realise I had picked on a super-fan.
So there are no other things the club can do to generate revenue other than changing the kit?
Kids want the new kits and pressurise parents to buy them. Parents make sacrifices to buy them (missing a few games) and then think "I haven't really missed that at all" and evetually stop going altogether.
Thus, if new kits were priced comparitively I wouldn't have a problem with them.
