Enrollment in Verizon's Auto Pay and paper-free billing is required for Verizon bill discount of up to $10/mo off each eligible account or line, up to 10 lines max on select plans. Visit Auto Pay FAQs for more info. Please note: Offer is for first-time enrollees. Verizon customers currently enrolled in Auto Pay and paper-free billing via other methods (e.g., ACH or debit card) will not receive additional Auto Pay discounts for re-enrolling using the card. See the Verizon Visa Credit Card Rewards Program Terms & Conditions for details on ways to lower your bill.
I personally already have been enrolled in Auto Pay, but for those of you that haven't it seems like this may be worth it. It also seems like the rewards are decent, with 4% on grocery store and gas purchases, 3% on dining purchases, including takeout, 2% on Verizon purchases, and 1% on anything else.
