What do you need to pay attention to when purchasing mobile phone holster?

Investigation and reference of market prices of related similar goods should not be based on one-sided word of service provider.

In the purchase price, it is necessary to analyze the cost and price to their advantage.

If purchasing in competitive bidding, analyze the price and quality of different suppliers and purchase from them separately to get a reasonable and fair price.

In the selection of bidding, do not regard the lowest price as the best service supplier, must choose a customized, production, delivery, after-sales and other aspects of the service supplier can provide support for the best.

So we usually choose manufacturers or manufacturers who offer us very low prices, rather than large wholesalers who offer us very low prices

Because the former in product quality, supply assurance, after-sales service, promotional activities and other sponsorship will be more marketing costs support.
