教授讲了risk of price discounting。 第一这样会导致大家停止购买正常价格的商品。举了一个家具公司的例子，他们在12月有个非常大的促销，几乎所有的商品都打折。过了几年，公司发现顾客在一年其他时间不买他们的商品，就等12月打折时候买。另外一个risk是大家会认为打折商品质量就比较差。举了汽车公司的例子。为了促销新款汽车，打折了。然后顾客就会怀疑是不是因为零件有问题，质量差才打折
The lecture has discussed two risks of price discounting. First of all, it will prevent the customers from buying products with normal price. The professors talked about an example of a furniture company. There will be an annual discount season of the company in December, when almost all the products are on sale. Gradually, the company has realized that customers do not buy their products until the discount season. The second threat is the misunderstanding of customers that products on sale are of worse quality. Take a vehicle company for example. Although the original purpose of the discount is to promote a new brand of cars, customers consider the new car has some problems with spare parts and are thus with extra discount. (123 words)
