If you're looking for Grey Vinyl to order from Germany (or anywhere else, too), you can either go with flight13.com or greenhell.de. Both sell the Grey variant on 180g for 19,90 €.
It doesn't matter anymore where you buy since both shops now have free deliveries for orders abover 50 €, but i would recommend flight13.com as they have a better policy (if an item is unavailable and you have to pay less than 50 € for your order, they still won't charge you with postage - greenhell.de however does).
I ordered mine at flight13 along with some other records. Looking forward to this record as well as the Berlin Show.
