Query: Think before you purchase Microsoft Office Home and Student version from Amazon.com

We purchased a new laptop and downloaded the trial version of Microsoft Office on-line. The trial ran out before we ordered the permanent software. When we went to order it, one of the options that came up was Amazon.com at a much cheaper price than downloading it from Microsoft. The product came promptly -- and we could not load it on to the computer because there was no product code. To get any help from Microsoft we would have to pay $49.95. We contacted Amazon.com who very quickly replaced the software, however it still has no 26 digit product code required to download -- So it appears that in order to load the product on to our computer we're going to have to pay Microsoft for service -- so we've wasted over a month and not saved any money. This is not the fault of AMAZON.COM. They have been very accomodating.
