Hello .Good day.The pricing can be upto the designer and how much he wants out of it,is his satisfaction. But smart seller goes by volume and not by fixed price. The pricing is fixed globally. My humble suggestion is the pricing can be varied(less or more) according to the economic conditions of the particular country . when the pricing is less in economically weak countries you can count profit by volume selling. So it is upto the decision of the maker or designer to fix different pricing if he want to be globally successful.
Kudos to all good designers and skinners.
