The price for a product is set by the manufacturer, distributors, and retailers. Not sure how you intend to "set" a price for someone else's product.
Also, and more importantly, there is far more to the price of a product than the cost of the components. The components are a very small part of the total price. Don't forget manufacturing, procurement costs, R&D (this needs to be recouped), marketing, packaging, distribution, customer support, various overhead, etc, etc. And of course, somewhere in there all the parties involved also need to turn a profit.
