Why do we carry out the purchase of the product

There are a lot of products sold in the market. When we know some brand products, the most important thing is that it is its price ratio. We know that the society is quite different from the past. When we buy things before, we may be able to get strict quality assurance as long as the items we buy are more expensive. But now it will not be like this. We will find that there are many products in the sales process, even if the price he sells is very expensive, but the quality of its products can not be strictly guaranteed. Because people now pay much attention to profit, and sometimes the advertising is big, he needs to add this part of the cost to the product. So in fact, the quality of the product is not as good as we think. In fact, the sale of energy-saving products in the market, in general, like a variety of energy-saving equipment, a lot of sales of enterprises. However, there are still a lot of companies willing to cooperate with the firm. Why do you all feel that the quality of the company's products is better? In fact, the main reason is that we will find that it is less invested in advertising in the process of production. The main investment is the product in the research and development, so the product in the production, the quality of the product can be strictly guaranteed.
