Unfortunately it seems very difficult to find this product in France or even in Europe. Either it is not in the catalog or not in stock. I tried to purchase it from a US website, but shipping fees are very high for Europe, around the half of the price of the product itself. Does anyone know a website that would ship this product in France for a reasonable price? Thanks for your help. -- Jeremie Le Hen Humans are born free and equal. But some are more equal than others.
