This boxset has been deleted for quite a while, and is selling for some really silly prices. I should know, i sold my boxset at xmas for £200!
It was with real regret though, since i love this series. But i was hoping that it would eventually get re-released. Periodically i check to see if it is, and to my shock i have found that Amazon are selling it (with free postage) for £54.79. I have just booked one. But i cannot find anyone else who is selling one apart from Borders for £79.99 (and it says unavailable on their site). I do not know whether Amazon have made a mistake, but everything went through OK.
