This is a very expected answer. What I hear from you is that Samsung just posted Verizon Wireless' Black Friday deal on their web site at their own.
Considering that I have triple-checked with Verizon wireless' representative in the local store and was assured that "Verizon Wireless will honor Black Friday deal" if I order the phone from Samsung.
Also, considering all screenshots that I made at 11/23/2018 from both Samsung's and Verizons' web sites (including the installment loan agreement with Verizon), you just confirmed what I think about Verizon honoring its own deal.
Thank you for the answer.
