Businessmen trapped in the "wrong price door" for the fault pay should be negative geometry?

Recently, Dangdang has three consecutive wrong price events, these three accidents are caused by the input errors of the relevant staff.　　Three wrong price events, so that dangdang into a very passive situation, although for each of the wrong price incident, Dangdang has given a corresponding compensation policy, but consumers seem to still refuse to give up.　　The "Wrong price" event can not be denied is the result of enterprise's own negligence, but on how much enterprises should bear, some professionals also expressed different views. Anti-hooliganism, a lawyer, said that with a 1800-yuan set of books as an example, if the site shows the original price is 1800 yuan, when the plan is sold at 50 percent, but the final result of the operation of the error led to the display price is 50 yuan, in the consumer price of 50 yuan after the purchase, Dangdang realized that the error, the book back to normal prices , such corrective action is allowed, "not to calculate the unilateral cancellation of the contract", because the wrong price contract itself is ' a major misunderstanding ' under the premise of signing.　　If the merchant wants to recover the books that have been issued, the law is also supported, because the consumers use the price operation error "unjust enrichment".　　Other lawyers also said aside from the legal standards, media and consumers to the business or to give a certain understanding, businessmen have for their own fault to give consumers a certain spirit of compensation, for the business error should be punished, but still pay attention to the yardstick, excessive rights may be judged "unjust enrichment." In fact, in the online shopping industry, "wrong price" has never been eradicated, Jingdong Mall, Amazon has also experienced the "wrong price" obsession, but for any industry in any enterprise, mistakes are unavoidable, and the greatest significance of such events is to standardize the healthy development of the industry, only from the legal or emotional judgments are unfair.
