Finally got mine from Amazon UK. Why I didn't buy it from there two years ago, saving myself much bother, is a mystery. (And yes the DVD is worth holding onto for the extras.)
When it looked like the disc was coming from Amazon, I cancelled my UK order--but when it never shipped, I reinstated my UK order and now it's finally, actually coming. Never had this happen before and don't know why I didn't just order the region free UK disc two years ago when it became available.
