$7 difference per phone, two phones, $14 per month. Over two years that is over $300. I choose to be frugal and save where I can.
Black Friday was android focused. Cyber monday was iPhone focused. The Moto Z3 was the only android that had a sale on Monday along with the iPhones. It just so happened to be cheaper than the black friday price.
There was supposed to be no "chance" as the phones were within the 14 day window of the price protection policy that Verizon has in place. Also, Verizon never indicated there would be any issues with the return and reordering them.
