As one of its daily deals, Best Buy has cut 40% off a selection of Blink video doorbell kits. The Blink Wired Doorbell 2K+ is $29.99, for example, down $20 from $49.99. Alternatively, you can pick up the battery-powered Blink Doorbell 2K+ with a Sync Module Core for $47.99, a $32 discount from $79.99. The standalone Battery Doorbell 2K+ add-on is also $41.99, but spending the extra $6 for the Sync Module bundle is better value for new users. Shipping is free on all orders for My Best Buy members, too. The deals end today. Shop Now at Best Buy
