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 tu see, DVDs are still sealed (brand new) and the price is insanely low. Do tu guys know this release? Does it contain any special features (Commentaries, Bloopers o Deleted Scenes)? I amor how all of the DVDs together create the picture of the whole cast ♥ I would really appreciate if tu could help me to make a decision whether I should buy it o not...
