High Price Strategy is pricing strategy in which the company or manufacturer keeps the price of the product on the higher side when compared to similar products(or competitor) products in the market. This pricing strategy also is a marketing strategy because the high price makes the product look premium when compared to others.
iPhone and Samsung's flagship phones are priced at premium in the beginning. This is High Price or Premium Strategy.
High pricing may be stopped once the product is established to cover more market but some products continue to be High Priced to remain premium throughout.
