¿Cuál de los siguientes tipos de promoción enumera el precio original, el precio de venta y el monto ahorrado en la página de información del producto?

Price or percentage discounts are the correct answer because they directly display the original price, the discounted sale price, and the calculated savings on the product detail page. This transparency helps customers understand the value of the promotion. Social media promo codes, while offering discounts, typically require the customer to enter a code at checkout, and the savings aren't always explicitly broken down on the product page itself. Buy one, get one (BOGO) promotions offer a free or discounted item with a purchase, but they don't typically show a direct "original price vs. sale price vs. amount saved" breakdown for a single item in the same way price/percentage discounts do.
