Here’s how it works: You must trade in any working smartphone, then purchase and activate an iPhone 6S or iPhone 6S Plus with two-year agreement, Sprint Lease or monthly installment plan for customers new to Verizon, AT&T or Sprint.
You’ll receive up to a $200 Best Buy gift card simply for trading in your old smartphone. Then, you can score a free $200 Best Buy gift card if you’re a new customer to Verizon Wireless, AT&T or Sprint. If you qualify for both, you could be walking away with a new phone and up to $400 in gift cards.
This offer is available in-store only at Best Buy locations. It’s valid through Oct. 3. Visit Best Buy’s website to browse full promotional details and exclusions.
