When I checked a few minutes ago today (Monday, Jan. 15, 5:30pm ET) for my upcoming cruises in late February, the Classic-to-Premium drink package upgrade cost for each voyage had dropped from $13.99/day before to $9.99/day now, and the Premium internet upgrade for 1 device was on sale for less than before too (now $4.99/day). I booked both. There's no indication as to whether this is a one-day sale or a longer one.
