No! This is just wrong!
How can a retailer expect to stay in business by providing "service", let alone "service" that customers benefit from?
Why, it flies in the face of decades of tradition in the retail commerce field. Even the esteemed House of H&K ("Because we hate you. And you suck.") knows this would never work.
Before you let Sears put that dishwasher in your house get it checked out for remotely-activated web cameras, hidden RIFD chips, caches of enriched uranium and any other contraband you can think of. That "service" must merely be a ploy to get the nefarious machine inside your house where the real deamons will be unleashed.
I'm hoping you, your wife, and your dishes are still safe enough to read this.
stay safe.
