This isn't so much a "PSB to Axiom" comparison (we know how that works out) but measuring the impact of shipping one system at a time to the other side of the planet vs. shipping a containerload to a distributor. Within North America the cost premium for rapid shipment of a single system is pretty low, but as you get further away from NA the equation doesn't hold up so well.
Remember the guy from Oman ? Shipping costs >> speaker costs ;(
The fact that these are a previous generation of PSB with a smaller center channel doesn't help -- even Axiom can't always compete with clearout prices
