We have seen lots of deals on Echo Dots, and often these devices are given out for free. I’m sure there’s plenty of people out there who have way more than they can use. If you need to get rid of them then Best Buy has a deal that can make it easier than trying to sell them on eBay or through other avenues. They are offering a $20 Best Buy gift card for every Echo Dot 3rd Gen that you trade in. You can see the promotion here.
