Which brands are available in shops in Dortmund?

Hi,
You maybe don't know but I moved to Dortmund. This is why I stopped for a time making models and this is why i sold a part of my big collection.
Now my question. Do you know which model brands are available in shops in Dortmund? I saw in the Müller there are Schleich(I'm not interested in this brand) and some Papo models.
Maybe are there any shops which sell more Papo or Mojö or CollectA?
