I think we have to give suppliers the leeway to fix prices according to the market. They have to operate with the realities, not as charitable institutions looking for equitable situations.
The Quando is a popular bike with good demand in the UK, so it can support a markup in accordance with that demand. the same goes for the popular Torq.

Overall, like any business, I'm sure they aim to create a viable whole which can be sustained, and how the margins are apportioned is determined by the marketplace through customer demand.
Ipods aren't cheap, but there are many other players just as good that are, again prices set by the market demand.
