At participating Best Buy locations, trade in any working tablet and get a $150 Best Buy coupon to be used on a new Surface Pro 3 Tablet. Plus, you'll also receive at least a $50 Best Buy Gift Card. That's the first trade-in deal we've seen on this tablet at Best Buy and yields some significant savings. Some exclusions may apply, including eReaders. To qualify for trade-in, the device must power on and be considered in full working order. (Trade-in value will vary.) Deal ends April 18. Coupons expire April 25.
