Multiple buyers can participate, delivery is not guaranteed, and no priority access is typically offered versus open auction buying. This describes which type of deal?

The correct answer is Auction Packages because this type of deal allows multiple buyers to participate, with delivery not being guaranteed, and without offering priority access over open auction buying. Auction Packages typically involve inventory that is available for bidding in an auction environment, where multiple buyers can compete for ad placements, but there is no certainty that the campaign will win the desired impressions. This structure is different from Preferred Deals, where a fixed price is agreed upon, and Amazon Publisher Cloud (APC), which is focused on premium inventory with a more controlled setup. The lack of delivery guarantees and priority access in Auction Packages differentiates them from these other deal types.
