It looks like Frigidaire is delivering their new models later this month, and Lowe's is clearing out the "old" models.
You need to put in your local zip code to see the reduced price on these models. PLEASE NOTE that not all models are available in all areas, so this is YMMV. The cheaper models have a much greater than 50% savings; however, as you get into the more expensive models the savings is less than 50%.
FrigidaireŽ 5,000 BTU Window Room Air Conditioner (Model: FAX050S7A) was $220, now $96
FrigidaireŽ 6,500 BTU Window Room Air Conditioner (Model: FAA074S7A) was $307.69, now $138
FrigidaireŽ 10,000 BTU White Air Conditioner (Model: FAC107S1A) was $416.92, now $158
FrigidaireŽ 10,000 BTU Slider Casement Air Conditioner (Model: FAK104R1V) was $553.85, now $359
FrigidaireŽ 18,500 BTU White Air Conditioner (Model: FAM187S2A) was $630.77, now $299
FrigidaireŽ 25,000 BTU Window Room Air Conditioner (Model: FAS257S2A) was $781.54, now $399
There may be other models in your area. These are all I could find when putting in zip codes for California and Connecticut.
EDIT: YMMV PEOPLE! I tried some more zip codes. Mississippi, Florida, Alabama all appear to be full price. Texas is on sale. If it says "Arrives in store on or before June 22, 2008" then you're SOL and the AC's are full price.
