None of it would make a blind bit of difference. Unless they chop prices at the knee (and even then there is no guarantee), it would be a huge waste of money. Interest is generated on the pitch, you can't force people.
How many times have we seen it where the city is blitzed with info about an upcoming match where there are special deals, 25k+ show up and we invariably lose. All the goodwill was lost and the next game there were 10k less in the ground. Ultimately our "product" is a football team, thats what sells. What MR has done in terms of creating goodwill and interest is more than any amount of marketing could do. If there is spare money then it needs to go on players, not entertainment, thats what will get people back. And it appears we have very little money, so why we'd divert what we do have onto marketing schemes when its whats on the pitch that attracts and retains "customers"- beyond me. If you're rolling in money- fine, have a few buses going around giving out pamphlets, until that time it would be a waste.
