If you are planning to build a business or even if you are just a consumer, I believe you should be aware of
pricing strategies used by most sellers. If you want to build a business this can help you dictate a pricing point for your goods or services and as a consumer this might help you be more responsible in buying.
Ideally a buyer must know the price of the item he wants to spend because maybe every store has a different price. This is useful so that people are not tricked because usually in the conventional market the price of certain goods can be different and I myself have experienced this. But to test this we need to look at the same product as the level of production, packaging and so on because if it is different then I am sure the price will vary.
I take the example of mineral water and try to make a purchase at the airport so the price is very expensive compared to the selling price at the usual store. This shows that a product can be different in price just because of a place, even though there is no difference at all in the form of packaging or production costs.
