Of note, Amazon has the UK Cut for $13.99 with free shipping for Prime members. (Non-members can spend $25 or more to qualify for free shipping; otherwise, shipping costs $2.98.) Although it's region-free, it will work only on Blu-ray players that support PAL and 50i.
Amazon Prime membership is $79 per year; however, Prime is free for college students for six months, and free for parents and caregivers for three months. (Note that currently there's a waitlist for Amazon Mom.)
