- Free droid pet - you'll have a collection of these fairly quick if you play regularly but one more isn't a bad thing
- Double XP: May 3rd through May 10th, then again from May 27th through May 30th.
- Free level 60 character: Apparently if you start a free trial by May 30th you get an insta-60 to run through the current (and expanding) Knights of the Fallen Empire story. That's pretty nice.
Based on those perks, if you're at all interested in some Star Wars computer RPG action it's a great game with a great story for each of the 8 classes and it is completely playable as a free player.
