But I see an interesting parallel between clothing and media, in terms of "trying them out," if you will. Over the years, Amazon has (at least anecdotally -- would be interesting to confirm this empirically) adopted a try-and-return policy on a lot of clothing, taking a hit on the shipping so that people can retain the "in-store experience" of making sure everything fits. Why does that necessarily have to be different for books and other media? Is it just a question of physical weight + price?
