Walmart offers the Microsoft Xbox One Wireless Controller, model no. S2V-00001, for $49.96. (Amazon charges the same price shipped.) Opt for free Site-to-Store pickup to avoid the $4.97 shipping charge. That's tied with our February mention and the lowest total price we could find now by $6. It features vibration feedback, an expansion port to connect other devices, and 30-foot wireless range.

Update: The price has increased at Walmart; however, Amazon still offers it for $49.87 with free shipping.
