It absolutely does at Derby - As mentioned earlier, the argument is that the pricing for a season ticket for a 'lesser' game is apparently set lower than for the 'better' games. Obviously that's not really the case, the STH sees it as x / 23 but that's the sell....
The system 'claims' that season tickets are priced variably also, so let's say that your Fulham ticket is priced at £18 worth of your season ticket and the Rotherham ticket £9, then a season ticket is still the cheapest way to buy a ticket.
