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 should not be considered by beginners as it will not be received well by the customers
when you are starting out you do not have a name for yourself just yet and the customers will not be very keen on paying money for nonexistent value just yet so if you are just starting out scrape this idea immediately
