Well no, it's sold out
you're such a nitpicker
"oooh the sales aren't as good as they used to be because I remember buying this limited edition DVD which is now sold out and they don't have
that in the sales any more"
Truth be told, you can get almost the entire Arrow catalogue in HMV for 5 for £30 or Fopp at £6 each. All of their DVDs are also 2 for £10 in HMV or £5 each in Fopp.
