If you're upgrading your current phone on Verizon, the carrier will snip $100 off the asking price of any iPhone with an "X" in its name -- as long as you hand over your previous phone. However, if you're switching from another carrier, or adding an additional line of service to your account, that discount rises to $300. Once again, you'll need to trade in your old phone to get the sale.

This offer replaces a much better deal to buy one iPhone, get an iPhone XR, or take up to $750 off any iPhone 'X'.The offer is available now.
