Never ever EVER look at the percentage discount. It is nothing but a red herring. Just look at the bottom line - what is the product/event going to cost, in the end ? That's all that matters. The percentage discount is based on the full onboard price and they never disclose what that price is, prior to the cruise. Currently, if your Deluxe Beverage Package is $51 or lower and you are interested in buying the DBP, GET IT. It's more than likely not going any lower than that. Also, you must realize that, in addition to the $51 PP/PD, they are going to tack on another 18% gratuity, so it will be even higher than $51...but that's going to happen no matter what price they are charging.
...and finally, even if the price does go down after you purchase the package, you can always cancel what you have and rebuy at the lower price.
