I just spotted this deal online. Save 20% on a Verizon smartphone purchased with a device payment plan when you use code SAVE20. This reportedly works on any smartphone purchase.
According to comments, the deal won’t work if you already have an employee discount on your line. Verizon has also been promoting a SAVE100 discount code on new devices which expires 11/2/16 and offers a flat $100 saving.
This 20% deal produces larger savings for most devices. Unfortunately, I don’t know when this expires, so if you’re in the market then it’s best to purchase sooner rather than later.
