Rolex Puurchase in DFS

[Astro]

Was in Soeul recently for holiday and chanced upon a Rolex in the DFS and wanted very much to get it as the price is cheaper as compared to those sold in Singapore. Wifey said since I am going to Europe soon i,e, Frankfurt, Germany soon. It will be cheaper to get it over in Europe. So I go along with the argument but was told by my colleague that is not the case. Was wondering if anyone had purchased any watch in the DFS store in Frankfurt and indeed it id cheaper to get a Rolex there. Not too sure if I have missed the boat in Korea recently. Thanks
