I bought it at the Sears store in Erie, PA. It was brand new in the box and works great. I was actually there shopping for TVs and saw it on the way out. I got the impression while shopping for TVs that clearance/markdowns are handled at the store level.
Is this the store at the mill creek mall? Can you upload a receipt? also, it would be great if you can give us the exact address and the phone number of the store you got it at!
