Gw mau tau Promotional pricing dari Penentuan harga. Jelasin dalam bahasa melayu

Promotional pricing refers to an instance where pricing is the key element of the marketing mix.

The price/quality relationship refers to the perception by most consumers that a relatively high price is a sign of good quality. The belief in this relationship is most important with complex products that are hard to test, and experiential products that cannot be tested until used (such as most services). The greater the uncertainty surrounding a product, the more consumers depend on the price/quality hypothesis and the greater premium they are prepared to pay. The classic example is the pricing of  Twinkies, a snack cake which was viewed as low quality after the price was lowered. Excessive reliance on the price/quantity relationship by consumers may lead to an increase in prices on all products and services, even those of low quality, which causes the price/quality relationship to no longer apply.
