That's a Polish edition (Region 2 and there's no english subtitles, still I think that prices are ok). For example: you can get BOXSET with series 1-9 + Special: "The Gateau From The Chateau" + Special: "Pregnancy" + Special: "The Best of 'Allo 'Allo" for 202 zl (about 82$ or 42 pounds) + delivery.
