amazon.co.uk the alien quadrilogy is only £10.07!!! with free shipping, that's only like $15 USD, that's the first time ever i have seen something cheaper in the UK than US, lol.
AVP, 2 disc unrated is £4.99, so that's $7.50, so a bit more expensive
and AVPR 2 disc unrated is £5.47, which is $8.24, again more expensive, but adding all 3 together it's still cheaper in the UK
