I received an email saying that the deluxe beverage package is on sale this weekend 'up to 30% off'. When I click on it for my cruise (Anthem of the Seas, NJ to Bahamas, March), it says price is $48 which is 20% off. I thought the deluxe package was normally $55. If $48 is 20% off, then the price was jacked up to $60. Does RC play around with prices like this? I swear full price was $55 last week or so.
