I am so shamelessly hooked on this store. It's like the German answer to Longs Drugs, back before…read morethe CVS takeover. Seriously, anything you want for the household is available here, and cheap.
A small sampling of the things I buy here: cat litter, hand soap, body cream, shaving gel, laundry detergent, brotaufstrich, razors, eyeliner, the occasional cute headband... and so much more.
My only regret? I wish there was a DM closer to my new flat. Although... that might very well be my downfall, so maybe I'm better off having to make a trek here or to Hermannplatz.
The only complaint about this store is that there are sometimes far too many people and there's only one line open most of the time, but in spite of that, service is still generally friendly and fast.
