Absolutely agree, which is why I don't push it. Plus, it's priced well above the average photo order we usually receive.
Twice I've done it, both weddings, and in both instances they ended up spending hundreds of dollars on the CD/DVD, plus the press-printed wedding album, plus prints family wanted, all above the cost of their wedding package.
What I did learn was that for the most part they didn't care about doing their own prints - they wanted images they can put on their websites, facebook, and email to their friends and family.
That said - how is this any different from me sending a politician or real estate agent's photo to the local newspaper, only to have it mangled and stretched once their design geniuses get done with it? I'm sure no one thinks the newspaper killed the photo
