Verizon wireless online. Bought one iphone xr and got one free in bill credits also applied promo code SMART100 bringing the second phone down to 649.99. When buying on the website I also waived the 30 dollar fee for upgrading and adding a new line by customer chat. I plan on canceling a line and just having a new number for one. About the best deal I could fine as I need Verizon’s service in my area.
