I've gone a couple of years to a place south of Paris. Compared to some of the British or Spanish setups it was a pretty casual shoot, with four drives (two in the morning and two in the evening). Light breakfast and a very nice lunch included. Price was about $400-500 or so for the whole day with today's exchange rate. It was not per bird, but a flat rate for the day.
Contrary to some perceptions if you go to "regular" shoots rather than the "rent castle, need pair of Dicksons, etc. setups" there is a good deal of driven shooting out there thats not that expensive, especially compared to what a lot of Stateside guys want for a half-day duck hunt...
