Monoprice offers the 32GB Apple TV 4K for $124.99 shipped when promo code SD35 is applied during checkout. For comparison, it has a list price of $179 and this is one of the best offers we’ve seen all-time not bundled with another service.
That said, if you’re willing to sign-up for 3-months of DirecTV Now, you can pick up this model for $105 shipped. If you go this route, be sure to cancel the service prior to the 3-month commitment running out, or your contract will automatically be renewed. More details here.
