1) Value based pricing. Basically a product is priced based on the percepted value of the product by the people. This allows for more profit since sellers can offer higher prices. Higher percepted value means maybe the business is credible and has some associated value to it for example Apple products. You can argue they can be a bit cheaper purpose wise but since they are a big name, they can afford to price massively.
This pricing strategies has been an issue in certain areas in my country and I think it's based on personal preference that one will want to either take the price of a goods high or low. And one thing that baffles me is competition based pricing where you find people beating with price of goods and making it seem difficult for customer then pricing based on profits, some sellers just like adding up prices for goods inorder to get profits by all means whereas there's a stipulated price for that particular goods.
