¿Cuál de los siguientes tipos de ofertas promocionales puede ayudar a impulsar las ventas mediante ofertas de ahorro por tiempo limitado?

Offers, such as Lightning Deals or Deal of the Day, are specifically designed to create urgency and drive immediate sales through time-limited discounts. This encourages customers to purchase quickly before the offer expires. Coupons provide a discount but don't inherently create the same time-sensitive urgency unless explicitly stated as limited-time. Promotions is a broader term that encompasses various marketing activities, including offers and coupons, but "offers" is the most precise answer for time-limited saving opportunities.
