Buying 'Buffy the Vampire Slayer' Complete Series on DVD. I need your advice:)

For a very long time I was planning to get all of Buffy seasons on DVD. Since I'm from Poland and my DVD Region is 2 I avoid Region 1 releases (they are gorgeous but I'm afraid it will not work on my DVD player). Lately, I came across this version of Buffy, it's European release (look picture above) it looks very nice as 你 see, DVDs are still sealed (brand new) and the price is insanely low. Do 你 guys know this release? Does it contain any special features (Commentaries, Bloopers 或者 Deleted Scenes)? I 爱情 how all of the DVDs together create the picture of the whole cast ♥ I would really appreciate if 你 could help me to make a decision whether I should buy it 或者 not...
