Verizon's current "deal" for many of its Android phones is to drop the initial price by $100 when you upgrade on your current line from a previous model. Alternatively, you'll get a $300 reprieve when you switch carriers or activate an additional line of service. Either way, you'll need to trade in your current phone.

Unfortunately, this promotion isn't as generous as the previous offer to buy one Galaxy S9 and get another free, or $800 off the Note 9 or S9 Plus.
