Buy in price actually for a company here is $35 already a year ago  
for 2TB disks.
They basically have 2 shops selling well in Netherlands and Germany.
I'm not sure they like to get mentionned here, but knowing you know  
some German,
you should have no problems figuring out that shop name if you think  
well.

You seem to have no idea what determines prices when you buy in a lot  
versus just 1.
