Just looked up my figures for this, my 30% increase was an underestimate.
The price of £249 for a Kop ticket for the first season at the Walkers included a pre-season friendly, a cup match, two extra match tickets for 'guests' (worth up to £64 at A+ prices), free entrance to reserve matches, and discounts on extra match tickets. This was available with interest free credit.
Two years later when the club announced the new prices, they claimed the prices had been frozen for three years. But that was a lie for a start. Prices had gone up by £50 the year before, so the ticket now cost £299. They'd taken all the above extras away, and started charging another £79 if you spread the payments. Someone who'd paid £249 in 2002-2003 would have had to pay over £500 two years later to get the same thing. And this was marketed as a price freeze. Wankers.
