Amazon is running a new promotion where buyers of any Toshiba or Insignia Fire TV Smart TV can get a 3rd-gen Echo Dot for free. This isn’t a particularly lucrative deal, considering how cheap Echo Dots get, but if you happen to be buying one of these TVs within the next month, you might as well get yourself a free Echo Dot with it. To get this deal, just add any Toshiba or Insignia Fire TV Smart TV to your cart, then add any 3rd-gen Echo Dot to your cart, and finally use promo code FTVEDOT21 during checkout. This deal is good through July 22, 2021.
