Sadly, Tesco has stopped doing the Big Sleeve Editions for blu rays of various films - which is a bit of a blow for those of us collecting the Star Wars editions (TFA, R1 & TLJ) so far.
Though it seems a few online fans maybe coming up with their own versions (some nice artwork used)…

Good luck to them 😃
