Dear Sir or Madam,

My friend has been trying to buy Minecraft for months now.
As soon as she puts in that she is from Germany, an error occurs and I wanted to ask if it is a problem on your end or ours? 
I have tried to look into it as well, the moment I try to buy it for her an error occurs on my end too. 

I added a screenshot for you to see.

Thank you in advance,

Anastasia Fingerhut
