Is this trying to say "price" does not fully deliver customers' or producers' opinions to each other? Is it criticizing the limitations of price or for it? It seems the other way or not.
For example, if a person saw a refrigerator priced at $700 and not satisfied with its price, just going out of the store, then the act wouldn't deliver his opinion about its quality or fuctions more important than its price? Can you take a specific example?
ex)The principal means of market information for manufacturers or service providers is money or, rather 'price'. The most frequent way consumers tell producers what they think or feel about products or services is either by buying or by choosing not to do so. But price is typically a crude medium for communication. Poor sales, empty shelves or weakened profits do not easily direct producers or providers towards how better to adapt to changes in consumer demand except by lowering or increasing prices. From a consumer's perspective, walking away from a shop empty handed does not fully express the detailed character of specific dissatisfactions; nor can non-purchase commnicate any sense of what this or that consumer might have been prepared to pay for. If all we know or are conconerned about in our relationship to a product is the price, then 'choice' becomes a perfunctory act.
Maybe I gave a "big" question....
Or maybe you should wait a bit- there are hundreds of posts here every day. You have had several hundred questions answered, so please remember that.
If I don't buy something, they can try dropping the price, but there may have been other reasons for not buying it, none of which are communicated by the action of not buying- there's little feedback from not buying. I may not want it at any price.
