Who I have the same questioned this topic

I would like to upgrade to new phones for 4 of the 5 lines on my current account. I have been a Verizon customer for over 20 years. Does anyone have any experience good or bad with Verizon honoring a competitor's deal on new phone prices? I would prefer not to change carriers, but if it means saving a few thousand dollars, I suppose I will have to go through the headache of changing. Thanks in advance for any feedback.
