If you've been thinking about adding Microsoft Word, Excel and Powerpoint to your home office, this may be a good day to sign up. Today only, Amazon is offering a 12-month subscription to Microsoft 365 Family bundled with a $50 Amazon gift card for $100. The price of the yearly subscription is usually $100, so you're essentially getting a free gift card for signing up. The deal is only good through the end of the day and the subscription will auto-renew at the end of the year, so set a reminder if you want to cancel before that kicks in.
