One of my friends ordered an Ultegra or DA cassette from Competitive Cyclist a few years back. When he went to mount the cassette, it said "105" on it, so he called all full of attitude that they had sent him a 105 cassette in a DA/Ult box. When I broke the news to him, he felt so bad he called CC back, tracked down the CS rep and apoligized about 50 times.
