I live in Mumbai and I want to buy ONE DIRECTION stuff... where do I get it from?
The easiest way would be online. Try eBay or Kijiji. I'm not familiar with where you live, so I would suggest that.
Online. Try amazon eBay. Or go to a one direction fan site they should have merchandise, that you can order.
I would say online. It's probably the easiest way, rather than going/traveling where they do have their stuff.
