There have been a few titles that only seem to be available there.. this and also the Lori Lieberman disc as an example.
I stopped buying from them when they added a minimum purchase amount for international orders - back in about 2005.
Also - FYI - I'd possibly use Bullmoose, but I can't even load their webpage from a NZ IP address....
I understand how you feel...but let's be honest...you live FAR away from these distributors...I used to do the whole "boycott" thing on principle..but I caved in when I really wanted something...as I get older I realize that tomorrow is promised to no one...you might not have a chance to do something "tomorrow"...so I try to do it now..even if it hurts my consumer "pride" sometimes...but that's just me...I usually try to save as much as I can on every hi rez release...but this time I wanted the Bread and the Guess Who discs early..so I paid more for them from acoustic sounds..
