I don't think boxed and shrinkwrapped software has much value. I have bought MacDraw II (two copies) and BannerMania, both of which were shrinkwrapped, for very little in the past six months. The MacDraws if I recall came to $14 for both and BannerMania was $25 or so. Also, I got a shrinkwrapped PaperPort scanner for nothing from a friend.
Of course, if you've got something really unique then perhaps it will sell for more. If VisiCalc came in a box, it would probably sell for a lot shrinkwrapped (I'm not sure if it did). Also, some stuff is in demand boxed because people still use it (WordPerfect 5.1 comes to mind).
If it's a computer, of course, an unopened original box will fetch you something. Remember that company that was selling NIB LC580s a few years back?
