I can see why the club did what they did. Besides, not everyone can do away games on a Monday night.
I agree the current way of selling away tickets does seem to be a closed shop - there needs to be a way of ensuring that if you buy a ticket for an away game then you must attend and not just sell the ticket on to a friend etc..
I don't suppose writing an email to the club would make the slightest difference, but might be worth a try.
