Final answer:
The fallacy described, offering a free vacation to distract from the actual product being sold, is a red herring fallacy.
Step-by-step explanation:
The type of fallacy described is a red herring fallacy. This fallacy distracts the consumer from the real issue by introducing an unrelated topic or benefit. In the given example, being offered a free vacation to the beach if they drink ABC Soda is a way of diverting the consumer's attention from the soda's qualities or the argument at hand to the unrelated perk of a beach vacation. The red herring is effectively a diversion tactic that shifts the focus to a tangentially related subject, which is often more appealing or less controversial.
