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.

After three months, your account will automatically be billed at the $35-per-month base rate unless you cancel before the end of 90 days. You can cancel at any time and still get the full three months of service.
