Re: microsoft office
If the freeware open office isn't your thing then obviously your only going to have a few options and that is up to you which you prefer. You could either pirate it for free but illegal, check places like ebay/craigslist for cheap version of it from people selling but got to make sure everything is going to be included that you need. Other then that you can basically just google and shop online stores and look for the best price. If your able to you could apply for education/student version to get discounted pricing.
