Insane indeed. I found a dishwasher motor at a Sears outlet for ~$5 cheaper than anywhere else. But they didn't actually have it in the POS system, only in the online system. They actually found the motor in the warehouse and couldn't figure out how to ring it up. It was local, too. Like a ten minute drive.
I gave up, hung up the phone, ordered it from Joe-Bob's Appliance Shack or something and did dishes in the sink for three days. Cost me an extra $10 (with shipping. I can do math.) and probably added a week to my life.
