Thanks for everyone's input on this. Firstly let me say that I have had a place in France for over 20 years, love France ,and am not wingeing. But someone out there must be making a lot of money from electrical gear in France. One can buy good quality double sockets for £3.60 each in GB, whereas the equivalent French item works out from Castorama at £7.92. No wonder I see in all my french friends houses single sockets everywhere with mountains of adapters on adapters hanging from the walls. I am currently rebuilding in France and need to buy 50 double sockets , so you can see why I ask if there is anywhere else besides expensive Bricos to buy sockets. Marcel
