I had a computer with Vista and I finally put it in computer heaven. I bought a new Dell, Windows 10, I-5-4460 CPU @ 3.20 GHz, RAM 8.00 GB, 1T something. I had Microsoft Office 2007 on it and when the place I took it to for them to put all my old stuff on the new computer, the Microsoft Office 2007 got lost in the workings. Since it is so expensive to buy, I have been looking on ebay for a Microsoft Office program. My question is (since there are so many of them), are they legitimate? I saw Office 2010 for $29.99, Office 2010 for three computers which said something about they copy them and are packaged to ship without damage, but not the same Microsoft packaging for $39.99, I saw some with Master Key Code included, and since I'm not all that computer smart, I thought I should get someone else's opinion before I buy one. I really can't afford the $100.00+ ones as I'm in remission from pancreatic cancer and doing really well, except I get little glitches every now and then I have to pay for (like right now I have become anemic and have to do weekly iron shots), so I always have these stupid medical bills. If I'm looking, what should I look for in the description, or should I not look on ebay at all? Thanks for your help!
