Tracking Availability of everyday commodities

In our country availability to everyday commodities can make our day or waste our day.

My idea of this app is real time crowd sourcing using social media like Twitter tweets, Facebook posts/statuses, also big companies like PSO, Shell, Caltex can use this app to inform people that "WE HAVE PRECIOUS PETROL at ABC---XYZ locations"

Also people can confirm about the availability of the commodities and win points if they are right. Another view of this app will be price comparison of things, nearest location to get a thing they need.

Basic idea is making life a bit easy for people living a very speedy life so they don't have to wait 2 hours in a row of cars on Kashmir highway to get petrol worth 1000 rupee
