Pueden participar múltiples compradores, la entrega no está garantizada y normalmente no se ofrece acceso prioritario en comparación con la compra en subasta abierta. ¿Esto describe qué tipo de promoción?

Auction Packages (Programmatic Guaranteed) allow multiple buyers to bid on inventory, but delivery isn't guaranteed, and there's no priority access over open auction buys. This describes a scenario where buyers compete for ad impressions, but the publisher doesn't commit to fulfilling a specific number of impressions or providing preferential treatment. Preferred Deals, in contrast, offer fixed pricing and guaranteed inventory, often with priority access. Amazon Publisher Cloud is a platform for publishers to manage their ad inventory and doesn't directly describe a type of deal.
