Google Home Mini in Chalk color or in Charcoal color for $49. This is Google Home's answer to the Amazon Echo Dot, and is a miniature version of the Google Home. This voice-operated speaker is powerful enough to full a small room (such as a bedroom) with music, sports scores, news, Google searches, and tell you your Google Calendar schedule for the day. It can also control some home-automation devices.
Walmart is throwing in a free $25 Walmart gift card with purchase.
Here are the specs of the Google Home Mini, and here is a video overview comparing the Google Home devices.
