Final answer:
A temporary price reduction on a product's package is termed a promotion, not to be confused with predatory pricing, trade secrets, or trademarks.
Step-by-step explanation:
A temporary price reduction that is marked on the product's package is best described as a promotion. This is a marketing strategy designed to increase consumer demand and encourage immediate sales. Economists might refer to getting a 'good deal' as consumer surplus, which occurs when a shopper pays less for a product than what they were willing to pay, reflecting the personal benefit received beyond the actual price paid. However, if the reduction is meant to dissuade competition, it could be considered predatory pricing. On the other hand, terms like trade secrets refer to confidential processes, and trademark refers to protected brand symbols or names.
