It's true that this place is large, 5 or 6 floors of electronics stalls. However, every item I was interested in, a quick search on amazon UK revealed that the prices were on par with what I could get at home with an EU/UK warranty. So for travellers, be wary, it's not always a good deal. I was comparing headsets and console games primarily.
