Summary: MS Office Home & Business, For $220 ; you're not even buying a product. You get a Product Key with ' No Physical DVD ' software to actually own !!! Ms Office Pro, $400 and your purchasing a Product Code to download their definition of customer use .. MS office 365 ; what a joke , they're duping us into RENTING their product, for only 1 year, without even getting any Disc Software !! I'll use Wordperfect instead !!
