Fair enough. We'll never know how many have not renewed, or the reasons why people haven't taken up their ticket. With the economy as it is that will have a much more significant affect than the loss of payment plans. But increased prices and inflexible payment structures hardly help that situation do they?
I think what has not been taken into account here is that a lost season ticket holder doesn't just cost the club £328, it could cost them thousands of pounds over a lifetime. I know many fans that went every week but lost interest for one reason or another and they have not been back. Once you are out of the habit its amazing how expensive and futile football looks
