Ok, I would like to share my experience buying wood from Massiveholz on line shop which is based in Germany.
All orders need to be made via email and I must say there is a massive variety available. All wood I received so far has been great quality.
I asked initially for some wood samples, 10 strips of various woods 2 x 10 x 1000 mm. Then I placed a large order, however I received more wood in most dimensions (it seems that round everything to multiples of 10!) and some other dimensions were less or missing. I emailed Frank and I received the missing wood but also some more strips I needed and asked to be added on, free of charge.
Packaging was very good and I received all orders within a few days. I would think prices are competitive .
Overall this is an excellent place to buy your wood if you are this side of the pond.
