My only uncertainty is whether when a beverage package is purchased from European sales whether the pricing of the beverage package includes VAT, as generally you don't pay VAT twice on the same product (you could argue the drinks package and drinks are separate, although that's usually the business' problem rather than the consumers). My understanding is that in the US/Canada the beverage package doesn't include sales tax, so it's more clear cut that VAT would be applicable in places that charge it.
