Availability of Pimm's in Berlin

Now that the weather has turned properly summery, my thoughts have turned to the great accompaniment that is a Pimms and Lemonade. I've had a look in our local Reichelt with no success (they usually have all sorts of Brit stuff). Does anyone know where I can get some before the rain comes back?

Karstadt/Hertie sell it here in Munich, not sure about their Berlin branches tho, but worth checking out.
Pimms in summer rules!

I'm pretty sure I've seen it in the branches of Extra at Ackerstrasse and Edeka at Alexa

My husband and I found Pimms at Edeka in Alexanderplazt last year. Now that you've brought it up I want some too.

I'm going to be out and about today shopping so if I see it anywhere I will report back on here and let you know.

Thank you, everyone. It looks like this weekend's BBQing will be suitably watered.
