New Year deal: Samsung Galaxy S7 edge comes with a free Gear Fit 2
If you're purchasing the Galaxy S7 edge directly from Samsung's online store (see the first source link below), you can add a free Gear Fit 2 to your cart before checkout and that's it - you'll get the wearable without needing to register for it. If you're purchasing the S7 edge from somewhere else, you'll have to register for the free gift via the Samsung promo page found at the second source link below.
Best Buy also seems to be offering a free Gear Fit 2, but the info that it's currently providing is confusing. As you can see at the third source link below, Best Buy says that you can get any of the Galaxy S7, Galaxy S7 edge, and Galaxy S7 Active "with a monthly installment plan for Verizon, AT&T or Sprint" and receive a Gear Fit 2 at no extra cost. Plus, Best Buy is taking $150 off the price of the S7. However, the retailer is sending customers to the same Samsung promo page mentioned above, which has it that only the Galaxy S7 edge is included in the deal. We've contacted Best Buy for further clarification, but have not heard back yet.
