I've written about easyCruise before, and while it's about as bare basic as you can get on a cruise ship, who cares when you're visiting the Greek Isles for about the same price as your cable bill?
For bookings the week of October 21 and 28, as well as November 4 and 11, the cruiseline is offering this great deal, in partnership with Travelzoo.

As if the price wasn't good enough, the first 100 bookings will receive a free upgrade to a cabin with a window.
