This is a pretty good deal for a 3 Blu-Ray disc PAL region, and cost only $33 delivered.
Check out under keyword "bourne" on this site, the region free trilogy costs over $100. At JB its $69.
Make sure you use the studentedge link first to get the extra discount.
I think this is the cheapest, even compared to Amazon.uk (with currency conversion and shipping).
AUD$31.89 on amazon.co.uk delivered or alternatively AUD$32.76 at dvd.co.uk delivered, both will come much faster than cdwow.com
