Somewhat OT, but the high street Fopp price is now £49. HMV own-branded stores are still charging half as much again, but it seems that retailers have decided that early purchasers have now been sufficiently milked.
It just depends on how long someone is prepared to wait. The £14 price for Alien took 13 months. (but now in cheaper packaging, which I prefer anyway). It also has 5 discs so 9 blu ray discs for SW, will keep it a bit higher for longer. I wouldn't be surprised if it is £40 in the January sales. I would rather pay less for the separate trilogies. I would be happy to pay £14.99 for each of them.
