I think the prices of items in a shop should be related to supply and demand like in real life, So, The starting shop will not have very much hull, But will have a very high demand for hull because everyone will use it on their ship.
This will, Naturally, Cause the price the rise, And if this is a white listed server, And no one else joins. That shop will slowly return to a standard price as supply and demand levels off.
