Price determines value,value affects price.Good product only sells good price,ability with good quality,the brand is adjusted,ability truly reflects the value that the product contains.With the same kind of zipper products of raw materials production,zipper pull load time is more than other factory,pull head torsional strength better than other factory,if the quality is poorer than that of products on the price is higher,how to also won’t have customers.Any one thing has its advantages and disadvantages,and as long as the advantages outweigh the disadvantages,it is uwually very easy to succeed.Will the old customer be able to accept the fact that the old customer will not be scared away by the price of the plastic zipper wholesale  ,and if the customer runs away,how do you find the customer?The reasons for the increase are mixed.It is not only the question of whether the company has sufficient profit,but also the survival and development of the enterprise. Beginning don't expect all the customer accept the price increase, rising in raw materials, customers will certainly know, so as long as prices don't deviate from the market actual situation, most customers will accept it.Enterprise will not worry about customers because of price,because compared with the quality,customers prefer to choose”you get what you pay for”quality and price is proportional the truth,who also don’t want to really because of quality problems and loss of customers and consumers.
