question about code geass dvd

i'm looking to buy all my favorite anime in dvd collections and for most its 37 euro for 25 episodes. but for code geass its 35euro for code geass R1.
then 40 euro for R2 part 1, and 43euro for R2 part 2 >:( why is R2 split up in 2 parts and so expensive? or will this change in time and be merged into a single box?







on a sidenote, so far i bought collections for
berserk
claymore
ergo proxy
samurai champloo
trigun
deathnote

im really glad i bought them all. feels better watching them like this and i can lay back on the couch while watching them :P so far claymore+berserk+deathnote were the best. deathnote has the best looking boxset/dvd's and berserk has the best looking dvd menu's+music. (i disliked samurai champloo the most)
