I've had a think about this, and realised that of the 8 MP figures I've owned only two were purchases on a whim and the rest were things that I'd long anticipated and decided I would get with a reasonable disregard of price.

So I suppose it probably won't change my pattern because I don't really buy that many MP figures, and when I do I'm usually happy to not overly concern myself with price. My impulse buy threshold is somewhere below $100AUD so this higher pricing doesn't really change things for me.

For example, I'd pay ~$300 USD for a fully fleshed out MP Movie Starscream, because it's a design I enjoy. Whether MP BW Megatron is $300, $150, $210, $294.84 or whatever, it's above my impulse buy level so it doesn't change things.

The eight figures are
Hasbro: 2007 Starscream, Skywarp, Rodimus Prime, MPM-3 Bumblebee
Takara: MP-11 Starscream, MP-12 Sideswipe, MPM-2 Starscream, MP-28 Hot Rod

The two impulse buys were Hasbro Skywarp and MP-28 Hot Rod, and mainly because I came across them in stores for about $75 AUD.
