For in-store pickup only, Walmart offers the PDP Sensor Mount for Xbox One for $8. That's the lowest price we could find by $7. It allows you to attach Kinect to the top for your TV and features a dust/privacy cover.
Walmart offers the PowerA DualShock 4 Controller Charging Station for $13.77. (Amazon charges the same with free shipping for Prime members.) Opt for site-to-store pickup to dodge the $4.97 shipping charge. That's the lowest outright price we've seen and a current low by $9, although it was $4 less after a gift card last month. This station charges two controllers at once and includes an AC adapter.
