Target offers the Haier 5,000 BTU Ceer Mechanical Window Air Conditioner for an in-cart price of $99.99. Order via pickup to cut the price to $89.99. That's $22 under our May mention and the lowest price we've seen. (It's the best deal today by $10, although most merchants charge $135 or more.) It cools up to 150 square feet and features two fan speeds. Deal ends July 15.
