25 N to exit 402. Go west till you see the small sign on the south corner, leaning against the light pole. Definitely call them first and bring a truck. You start wandering around and who knows what impulse buy items you might add to the list.
ETA: know prices before you go. You might think it's a good deal. Between the drive and cost, it might pay to buy new, or not.
