Mini-market UK-style shop in Dortmund

Hi everyone.
I am here firstly to join a brit speaking board and try to get to know the community out here.
I am moving fully to Dortmund in the next few weeks. I spent 2 weeks there recently and was told by many brits there that there was a need for a large well stocked british shop.
At the end of November, I am opening a Mini.markt style shop in Dortmund. It will be selling everything someone could expect to find in a small supermarket style shop over in UK.

Thanks so much am excited!! Hope to buy hobnobs & some decent porridge!

One year on what is the status of this shop? I work in Dortmund and would LOVE to buy some British products to bring home to my girlfriend.

Please provide all info on this shop! Cheers
