A while ago I bought a dish washer at Sears, and signed up for their installation for $269. It seemed expensive, but the expense was better than the hassle of trying to line up a third party installation on my own.
I wasn't home when the Sears guys arrived, my wife was. They looked at our old dishwasher and said that the hookups weren't to code, and they would leave, with our dishwasher if we didn't cough up another $250. What could my wife do? She paid.
They were in and out in less than an hour. I bet they find "code violations" in all the homes they do installations in. The Sears customer service guy I called about this was rude and completely
Frankly, Sears does not actually send their own employees out to do this work - they outsource it to local flunkies, and they absolutely do not care what extra charges those flunkies rack up. Not their problem.
