Pre-order the Matrix Trilogy on Blu Ray for £29.95 plus a further 10% off if you have a Virgin Credit Card. Less than a tenner for each film even without the discount.
If you don't then Amazon are selling it for £29.98 and HMV for £29.99. For me it works out cheaper to go with HMV as I get 10% Student Discount and 7% Quidco which works out as £25.11 but from what I've observed more people seem to have Virgin Credit Cards.
This is a review for the HD DVD set which was released in the US and the UK Blu Ray set is very likely to be identical although it may have slightly more special features as we aren't getting the Ultimate 5-Disc version over here.http://hddvd.highdefdigest.com/405/matrix_ct.html#Section5
