Instead prepaying for 4 months, you only have to prepay for 3 months to get a "free" Apple TV 4K while supplies last -- with free FedEx ground shipping. That equates to $105, a whopping $75 less than the Apple TV 4K's $180 price.

The offer has been going on since March, but ends today (May 31, 2018).
