When it comes to non essential products, particularly high end luxury goods, prices and costs may have little relationship.
To see this at work, in the most extreme way, just look at the luxury sunglasses market. Almost all the luxury sunglasses brands are designed and made by the same Italian company, Luxottica, on the same production lines, in China or Italy, and at almost exactly the same cost. But prices are set to suit the brand image. So Prada and Cartier are priced higher than Ray-Ban, just to keep the perception of different levels of exclusivity. Not because they cost more. There is actually no such company as RayBan, its just a brand within Luxottica, and Prada, Cartier etc do not make or design sunglasses. It's all owned and done by Luxottica. They even own most of the retail outlets, like Lenscrafters, Sunglass Hut and Target Optical, and many others. So they completely control price setting in every country. The Target Optical inside Target stores is a very clever move to make people believe that are going to the cheapest possible place, but the prices are still really much the same as the Sunglass Hut.
In the same way large international companies will 'adjust' pricing for different products and countries to maintain the right model/brand perception. They just accept different margins, volumes in different places, and average it all out. Works as long as you have a wide range of products and markets.
