Best Buy is opening up pre-orders for employees in the next few days. Should I pre-order my phone there and hope that we get it in stock. (iPhone 6S Plus Rose Gold 64GB) If I go that route I'll spend about $150 because I'll have a $200 Best Buy gift card to put towards the down payment for adding a new line. Or should I just spend $300,+ cash at the AT&T store? Does anyone know how much they send to 3rd parties? This is my first year at Best Buy.
