to avoid the $13.99 shipping cost. That's the lowest total price we could find now by $27, although we saw it for this price with free shipping a month ago (since expired). Sales tax is added where applicable. This air conditioner features a 2-speed fan, antibacterial filter, adjustable thermostat, and more.
Update: If you'd rather not venture outside, Walmart offers the very similar General Electric 5,000 BTU Window Air Conditioner, model no. AET05LQ, for $99 plus 97 cents for shipping.
