Garmins can cost a pretty penny. But good news for runners looking for a deal: the excellent Forerunner 255 is down to $250 ($100 off) for Cyber Monday.

Walmart is now selling the cheapest Vivoactive 5 we've seen so far, $100 off and $189. That's the same price as Amazon on a great all-rounder with an AMOLED display, 11 days of battery life, and more. (Only in Black)

SAVE $100: As of Dec. 2, the Garmin Forerunner 955 is on sale at Amazon for $399.99, that's a 20% discount on the list price.
