We have a treadmill for sale. It is about 5 years old, but of course it sat for the last 4 years and six months. The treadmill is in very good condition and shows minimal wear/tear. We bought it at Dick's Sporting Goods for $750. Currently it is in our basement (one flight of stairs), and you would have to come and get it.
We are absolutely open to reasonable negotiation. We are asking $200.00 (OBO). We also have the impact mat that goes underneath the treadmill. We paid $100 for it originally.
