Best Buy offers the Insignia 3.2-Liter Analog Air Fryer for $34.99 with free shipping. That's $45 off and the lowest price we've seen for an air fryer of this size. It features a 180°F to 400°F temperature range, automatic shutoff, and timer. Note: Orders placed by December 20 at 11:30 am ET are expected to arrive in time for Christmas.
