These guys are just one city away from the extended relatives. We talked with them and they are willing to truck items to us if we make a large purchase. This is where I found the GF icecream cones, icecream sandwiches, and GF phyllo dough (I haven't tried that one yet).
These folks were so nice, they threw in some freebies for us when we went shopping there as we spent so much and brought little JD along for the ride.
One word of caution though. The "Hammer Mühle" products often contain Gluten Free Wheat Starch (Glutenfrei weizenstärke)... so if you have issues with a wheat allergy on top of CD... BEWARE and DO NOT purchase.
We found that out in shop.
Hope that helps!
