I was trying to find child locks or known as "Kindersicherung" auf Deutsche. I went to a couple of…read morehardware stores and was unable to find any. One of the guys at the office said to try at DM and off I went. This shop looks like it has been recently opened and it's huge. Everything from drugs to cosmetics and tons of other household supplies and baby supplies. Sure enough they had a range of child lock products available in the baby section and reasonably priced. It was almost as cheap as buying on eBay or online stores. The staff here are helpful and surprise surprise there is actually staff at this shop ;-)) The range is extensive and the choice plenty. It is located in the upper level of the OEZ and whilst the store was quite busy at lunchtime it was quick to find what I needed and pay for it. Definitely coming back here again :-))
