Competition in its purest form

In Sanya, Hainan, China, there is a street near the bus terminal that has close to 20 double sided boothes with an assortment of products to sell to tourists who wander by.

What is interesting there is the model of competition. First : every booth sells a variance of the same objects: pearls, jade, chopsticks, plates, etc...

Second, the proximity of the booths to one another is never more than 1 foot.

Third, the prices are already on the low side. The perfect storm of negotiating and good prices. I have rarely seen the power of the walk-away be so effective.

Whose the winner ? The consumer ... and the manufacturing company that produces those objects for the 20+ booths.
