I don't know them from a bar of soap, but price and volume is not a successful model, no matter how intelligent you are. To be succesful they need to have multiple revenue streams, at different margins, at different volumes and offering different value - goods and services. Lastly they need a brand and community who values what they offer above the commodity.
The thing that cracks me up in the country, is there is a large % of the population value Quantity over Quality and lowest price is king. If anyone wants to debate this, just look at your balance of trade and debt to China, and waist line.
