In the context of advertising, what does "half-off sale" imply?

The term "half-off sale" specifically implies that all items are available at a discount of 50% off their regular price. This clear and direct messaging indicates that customers can expect to pay only half of the original price for every product being offered during the sale period. This is an attractive marketing strategy designed to draw in customers by highlighting the extent of the discount across the entire inventory, rather than on a selective basis.

Other interpretations of the term, such as limiting the discount to selected items or linking it to previous sales or inventory clearance, do not align with the straightforward implication of "half-off," which communicates a uniform discount across the board.
