Bought a new laptop for myself and thinking of purchasing Office 2016.

I'm a pre-U student and there will be many presentations to do.
I only need PowerPoint, Excel, Word. Which one is the best and cheapest that suits my needs? I don't care about the updates, just want the Office 2016 and use it for a longer period of time without having to pay yearly (I want one-time purchase).

Emphasizing it again :
1. PowerPoint, Excel, Word
2. One PC only
3. One-time purchase, not a subscription or need to renew after a period of time
4. Should be cheaper

Which should I buy and how much now?
