iPad 3 - do I sell?

So I have found myself hardly ever using my iPad 3 - I have a 64gb Wifi version. I use my MacBook Air all day (especially during the school year as I am in business school). I also have an iPhone 5 (planning to upgrade to the 6). I am interested in selling my iPad 3; I feel like I can still get some good money for it still. How do you recommend I go about selling it? And how much do you think it is worth (it is in near perfect condition)?
