If you’re trying to keep an eye on your blood pressure (can’t imagine why!), Amazon will sell you this Omron 7 Series electronic monitor today for $41 (after $10 coupon), the best price we’ve seen.
In addition to storing 120 readings on the device itself, this monitor can connect to your smartphone over Bluetooth, and sync all of your data to a free app (as well as Apple HealthKit), making it easy to track of your progress over time.
Not to stress you out, but we aren’t sure how long the $10 coupon will be available, so don’t delay.
