For in-store pickup only, and with stock varying by ZIP code, Target offers a $100 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's around $100 less than you'd expect to pay buying these phones on payment plans from their respective carriers, although we saw the same deal with a $300 gift card in March.
