Microsoft likes to push its Office 365 subscription service, and Google Docs is enough for most people, but if you pine for the days of pay-once-own-it-forever Microsoft Office, you can still buy it! In fact, today only on Amazon, you can buy it on sale. Pay $99 (down from $129), and you’ll have classic copies of Word, Excel, and PowerPoint, forever. You can even install it on a PC or a Mac.
