this is very helpful and based on this, it appears that the actual price increase in € value is not as drastic as the £ value, it is still relatively same price in Paris, e.g. for a K wallet... so not sure why they have to increase the £ value so drastically
Sadly I think it is less about us in the UK and more about discouraging tourists from shopping over here. With this price rise France (and mainland Europe) is again the cheapest place to buy H. I think I read recently that the low £ has made London a huge luxury shopping draw for tourists.
Trying to look at the positive, as Pinkfairyjade says, there may be more readily available stock now!
