For in-store pickup only, and with stock varying by ZIP code, Target offers a $300 Target Gift Card for free when you purchase an Apple iPhone 7 or 7 Plus for Verizon, AT&T, or Sprint on an upgrade or a new line of service via an installment billing plan. (Price varies by device and carrier.) Assuming you'll use the gift card, that beats our February mention of a $200 gift card and is about $300 less than you could expect to pay buying these phones on payment plans from their respective carriers. Deal ends April 1.
Note: Although you can set up your order online, you must complete your purchase by picking up your device before your retail store closes on April 1 to get this deal.
