Sympathetic to your cause...
Hello Greedo!
I totally hear you! For as badly distributed as the figures are here in the some parts of the USA, I can't even imagine what my life would be like up in Canada. I went to Japan in 2000 to visit relatives there. Imagine my surprise when I saw all of the last waves of Episode I figures there in huge amounts! There were tonnes of TC-14s, R2-B1s, Sio Bibbles, Amidala (Battle)s, and the rest. They also had all of the exclusives there as well- and get this... I found them all at Toys-R-Us! It didn't matter where I went. If there was a TRU, I stopped in- whether it was Tokyo, Osaka, Koriyama or wherever, they all had the same stock! I'm not sure what the collector's market is like there, but it would have been sheer heaven.
I suppose you have to go on the internet, as I often do, to find many of the items that you can't find, which sounds like an awful lot.
Meanwhile... my local Kmart has tonnes of the X-Wing Luke, Ketwol, DSE Han, Jedi Training Obi-Wan, pleasure tongue Jar-Jars, Bespin guards and Duros warming the pegs for $6.88USD each! They recently over-ordered on the Deluxe Luke and Maul sets and now THOSE are warming the pegs for $9.99USD each. I have a pretty good idea that they won't be getting the Leia or Amanaman or any of the last POTJ wave, which totally stinks.
