Kmart has a 5,000 BTU Frigidaire window AC unit for just $100 with free shipping code FREESHIP. This is the lowest price I could find by about $20. Also, shipping would normally be $18.95. This unit should be enough for small to medium rooms under 300 square feet, or about a third of my little rowhouse. Summer's coming and do you really want to go through another summer with that old, bulky, squeaky, leaky AC unit with the sharp vents at the bottom?
