NFLX certainly has a product that people want and enjoy. Not to mention they are the clear market leader in the space. I am a faithful subcriber of it and enjoy the ease of its use.
The same cannot be said of Radio Shack. There lies the big difference. I wont pay more for something I can buy online in my home and get a far far better price and will be at my door in a day or to. Or I can go to Walmart if I need it now.
Hopefully you can understand the clear difference.
