One day, I was wondering about why the prices for a product fluctuate as much as they do. It  really is a fantastic self-correcting mechanism the supply-demand. 

But it is not perfect. Often it takes time for supply to adjust to demand. It is really a hassle for everyone to adjust to new prices, specially to the consumer.

The idea is to have a box on tip of the chain that would report to the industry how many units of a product were actually sold during a period. This would be made to seemingly integrate into vendors managing software. 

I didn't thought these boxes would be necessarily enforced by law. Maybe the factories could negotiate contracts with retailers to use the devices, I think it would work best like this.

I think that, if there were enough boxes to be statistically meaningful, the factories could get a very good picture, and take action accordingly.

Now, I have little knowledge about how things are done in the market. I could be way off on this one. Perhaps there is already a way to accomplish this that I know nothing about.
