Rocks - they are in Chanhassen, MN about 25 minutes from me and I've driven over to their City Desk for local pick-ups five or nine times. The first time I was there their new building was just built, red clay everywhere and one of the Company Officers actually handled the details of my order.
Looking at their prices they strongly compete with anything off eBay. Their warehouse is 95% automated with robotic picker trolleys dropping bins of picked-orders off at supermarket style conveyor belts where the check-out count & packing clerks finish the orders for the robotic sleds to return.
look familiar to anyone?
