This is kind of the German Macy's, I come here for many years, love the friendly and real helpful…read morestaff, and best of all, they give you the "Tax Free" confirmation, meaning that everybody who lives outside of Germany does not have to pay Taxes in Germany, when the goods you buy are exported - did you know that? You just need this confirmation which you show to Export Customs when you fly back home.
That also means instant 19% discount of anything you buy since in Germany you have to pay 19% VAT on everything.
So I do my annual shopping here, find everything I was looking for, get my Tax receipt and I am out in less than an hour, that's what I call time effective shopping!!
