Classic Microsoft

Why is it they think up really great ideas but the implementation is always horrible? I don't know how they couldn't see this one coming:

"Microsoft and various retailers have teamed up to bring you cashback on
purchases made via Bings price comparison feature. There is a little snag though
— it seems that when you have a Bing cookie living in your browser, some
retailers will quote you a higher price than if you come with no Bing cookie in
your system."

Hell, that was the first thing I thought of when I heard it.
