Im in Europe, so I thought that if I don't find a coti to my taste here for sale or trade, than I will order one from Ardennes. But my question is, if I ask for a specific layer, say a Les Latneuses, LPB, or La Veinette, in 125x40 size, how much will I have to wait for one to pop up? One month? Two? Half a year? Or it is faster if I ask them regularly if they have those layers in any size for sale?
