You have a point about all the information you provided OP, and many businesses have collapsed due to the business owner knowing all this pricing strategy while some business owners that understand the pricing strategy don't know when to truly apply it to boost their business.
Having said that, when start a new business I believe using all the 3 strategies will help and the best strategy I believe it good to use for a start is the competition based pricing.
More likely, these forms to pricing are associated to certain stage in production. While all the categories to pricing could be very useful to producers, when you are a retailer, you really don’t have much choice rather than to use the cost based pricing where you get your determine what it took to get and transport the product, add some amount for profit and sell it off. Producers are the once that concerns themselves with competitive and value based pricing since, you don’t get much in value when you are breaking in the market and when the product carries just fine, then you can talk about value.
I think price of things matters for person to person because when we enter in the market, sellers judge us by our clothes and then they speak us value of thing in which we are interested. There are thousands of people who are poor but they like to stay clean and they wear costly dresses and shoes and they are buying the things at high price. There could be low price things if they use their mind but they only want to showoff and that is destroying them . Rich people always buy products from the brand and brand are earning from rich and middle class people especially because they want to show they are rich but actually they not and brand gave these products for free to the models .
