Costco.com has the Xbox One S wireless controller for $39.99 after manufacturer's discount valid 11/4 - 11/12 (membership is required).
I haven't checked my local store, but this price should be the same in-store, if they have it.
They also have the Xbox One Special Edition Dawn Shadow Controller for $52.99 w/free shipping.
