It's not a mystery, it's a secondary market, so eg for Dips away, there must have been 100+ blues with the required points who decided to make some money and sold their ticket for say £200. A few years ago I was sat next to some Japanese tourists for a Community Shield game at Wembley. I got talking to one who told me they had bought their tickets from a spiv for £100, face value on the day was around £30. In addition, we had thousands of unsold tickets but for some reason they were happy to spend the 100 on the day. So I don't think its the Club's fault just Blues on the make. I suppose if you've been to Klanfield 20 times it's no biggy to go 21 times.
