Setting RSP (Retail Shelf Price) for individual products, manufacturers and retailers usually take into account the prices of their similar products and that of the competition.
Another rule which allows them to cover additional costs is to raise the price of the product through the added value of the product itself. It can be the form of the product (e.g. a set of separately packed mini products) or packaging (e.g. a zip - lock that makes it possible to open and close of the product multiple times). We follow the principle that the shopper is ready to pay more, when he can see the benefit for himself.
