This is a pretty insane deal. I know it can be taken advantage of in store. Not sure about online.
Here's the math. New Verizon customers can get $490 of the V40 which is stackable. New Verizon customers also can get a buy one get one free on the V40 up to $750 off. The phone costs $980 to begin.
-490 = $230
Divide that buy 2 you get final price of $115 per phone. They have a similar deal on the g7 but the V40 is a much better phone I'm.
