A reasonably intelligent purchaser assigns value based on personal use and experience. I don’t think most people would be convinced that a motor vehicle offered for sale at $100,000 was a bargain just because the sticker said $150,000 when comparable vehicles sell for $50,000..
$76 for a drink package is a bargain compared to other lines. But it fails when compared to a $60 package that includes more than drinks. The irony is that both are offered by the same line.
No matter what Princess tells the consumer, a drink package is worth how many drinks I purchase at the per drink prices. Two beers a day at $8 each is still only worth $16. And ten fancy drinks at $15 each is worth a whopping $150. I assume most people can still do basic math.
