Browsing through my local CEX and spotted several copies of this boxset alongside the newer Force Awakens. Checked online and showing plenty of stock, though you would have to add postage if ordering online.
I didn't intend this to be a pun, but on reading it back - this is not the packaging I was looking for - is a bit close to the mark! I expected young Anakin & Luke in front of his domed house, but it looks like this Darth Vader fronted edition is the newer version.
It is CEX, so everything is preowned which I have put in the title, and the condition varies by item and store. I got lucky and found copies in "as new" condition. It is quite slim for 9 discs, roughly 2 normal bluray cases wide.
£25 seemed a good price so I bought instore.
Done a bit of searching for other prices:
Tesco - £40
Zavvi - £47.99 (older packaging)
Amazon - £38.99 (or £26 each for I-III, IV-VI)
HMV - £49.99
