The drop in numbers may partly be down to the special offer for the first two home games.

which could mean we failed to convert them into regulars...

True. It's not one reason - there are several which have been discussed at length over the years.

No, those that came are the general floaters. There are always a good few who only come if they get a freebie or a cheap ticket.

Your certainly correct in my case. I am unlikely to buy a season ticket or pay full price. There's nothing the club can do to change that but it is maybe worth the club doing one or two offers a season to swell the coffers.
