The Garmin Dash Cam 45 drops from $149.99 to $139.99 when you add it to your cart and proceed through checkout at BJs.com. Plus the shipping is free. This is the lowest price we could find for one of these cameras by $10. Like most dash cams, the Dash 45 will auto-record when it detects an accident. However, unlike most dash cams, it also has alerts for red lights, speed cameras, forward collision risks, and lane departure. Sales tax is charged in most states.
