At Verizon Wireless, with the activation of a new account or addition of new line on existing accounts, buy one Samsung Galaxy S7 32GB 4G LTE Android Smartphone for Verizon Wireless or Samsung Galaxy S7 Edge 32GB 4G LTE Android Smartphone for Verizon Wireless and get a second Samsung Galaxy S7 or Samsung Galaxy S7 Edge for $0 via this mail-in rebate and coupon code "S7-APRILPROMO". (You'll have to pay all applicable taxes and fees on both phones. The rebate will arrive as a pre-paid Visa card within eight weeks.) That's a future savings of at least $672 and only the second such freebie offer we've seen on these recently released phones.
