Snapdeal wasting money on Facebook

Why Snapdeal cannot beat Flipkart.com

Snapdeal.com a leading online shopping store in India trying to drive sales from Facebook.com using SMO (Facebook Advertisement).  In the world of E-shopping they are not alone, Flipkart.com is another best player. Both sites are spending money on Facebook Advertisement to get conversion. Both sites have the return policy/ money-back guarantee. But still Snapdeal.com got long way to go to be dominant player.

Snapdeal.com is running advertisement on Facebook.com. But they don't know about URL placement. How to set landing page.  In above image snapdeal is using ww. instead of www.
see the url below they are using now.
http://ww.snapdeal.com/offers/christmas?utm_source=fb_mobilestablets&utm_campaign=noncustsub90mob&utm_content=mobilestablets

Snapdeal doesn't have this kind of URL in their web server, so it return me an error "Invalid URL."

Than I try to run this url by adding another w in the url .

URL with www.
http://www.snapdeal.com/offers/christmas?utm_source=fb_mobilestablets&utm_campaign=noncustsub90mob&utm_content=mobilestablets

But this is also giving me a not found error.

And I am sure that their webmaster are not aware of Google.com/webmaster and because of this they didn't find this error yet and motivate me to write this all.
