Found an even cheaper source of DVDs – Australia! do dead cheap DVDs (mostly ‘cos of the strength of the pound against the aussie dollar – something like 1 UKP buys 2.77 AUS$) Couching Tiger, Hidden Dragon for UKP 13.56, Aliens:SE for UKP 8.41, or how about The Matrix for UKP 10.25, all including int’l p∧p.
Reason I found this site is because the only english version of the film The Final Countdown is on Region 4 (ie Aus/NZ) DVD.
They also sell episodes of Monkey (including one – volume 8 – with Jackie Chan and Sammo Hung?!?), and Friends very resonably.
