Well living in the UK it was really hard to get hold of these exclusive boxsets, but a kind soul I found through eBay was able to get me all of them. What I then did was amalgamated the 2 exclusives into one boxset and sold off the other one. Didn't need 2 sets with the same covers.
I have got the SDCC exclusive number 3 thanks to He-Man.org and now the Best But exclusive complete 200X series.
I am a happy bunny with all the DVDs released through BCI and now have every R1 boxset. Roll on the new film
