That makes it even better. I don't think of that.
Ordering from Verizon also charges you a $30 upgrade fee. This fee isn't charged when buying from Samsung. So for me, i as saved $30 on upgrade fee and $30 on taxes. On top of that, Verizon offers up to $480 for trade in but only $240 for my s5. Which isn't bad, but Samsung gives $425.
Once factoring that in, ordering from Verizon would cost me $245 more over ordering from Samsung.
Of course if you have an s7 edge for example then Verizon will give you $480, Samsung $425. But you also need to factor in upgrade fee and taxes (if applicable).
