How about with the encore series or other TF's that are not sold in Australia? I spotted so many of them whilst in Japan and many of them seem to be the same as another one but then they'd be a completely different price like for example Galvatron, the only difference I could see was that one had a yellow all spark and the other had a green (I ended up getting the green one). Plus they are not really sold in retail stores in Australia so it be hard for me to determine which is selling out more quickly? Oh and Alternators was another one, two seemingly similar alternators at two different prices?
