Been lurking for a while, thought I would make a contribution.
Been in France for the week.
Instore in Toys R Us are:
2507 Fire Temple 39.50€
4841 Hogwarts Express 45.00€
4738 Hagrid's Hut 30.00€
4867 Hogwarts 30.00€
All in stock at the Toys R Us 5 minutes south of CDG airport.
Also some of the supermarkets have series 6 CMF for 1.80€.
I traveled light with a big case and got a Fire Temple and Hogwarts Express for about £73, plus some series 1 CMF they had.
