Yep I noticed part 2 of the Blu-ray CE was down in price a few days back(Not sure why the DVD isn't as well), but also already had it, I think i got it in a previous christmas sale or I just had it I can't rememeber. As the last christmas sale it was reduced in price to I think £7, so I assume they are just trying to free up stock space.
I have actually recently purchased part 1 and 3 CE's (3 hasn't arrived yet, but it oes also have to extra/outer box), but they are both DVD versions so I will have to grab Standard edition Blu-rays at some point.
So you probably only have to wait a bit after you've fully given up
. I think there is a part 3 Blu-ray CE up on ebay but maybe a bit pricey (I'll grab link if intrested). Unfortunatly I think there was a full set (minus the extra box) going for a very reasonable price a week ish ago, but I'm pretty sure that sold.
