Amazon currently has a great deal on Eden of the East: The Complete Series. You can get the entire series for just $22, which is a fantastic deal. Trust me, once you pick up the series and get a couple episodes in, you'll be absolutely hooked. Of course, from there on out you'll have to pick up the movies!
So yes, a great time to get in on the series cheap, but be prepared to be sucked in and spending more cash later on!
