I'm considering switching and buying a new 12"PB this summer. If I buy one I'll need to get the Mac version of MS Office. I noticed that the discounted version of MS Office vX is no longer available from Apple. Now they want $499 for it. I was looking at eBay and noticed that some sellers are offering it new and unopened for about $250 or so. Other then the risk of getting ripped-off by a con artist, is there any reason to fear buying a new, unopened copy of MS Office off of eBay? Is there some catch that I'm missing. Some appear to be the full versions of the office suite - not just upgrade versions. Now that the promo is over, buying office online for almost 50% off sounds like a deal that is too good to be true. Any comments or advice? Thank you.
