On the indie side, delivery is worth actual money because their alternatives are to build their own e-commerce site (never goes well for nontechnical folks -- pay a bunch for a consultant to set up a site that never gets touched again, suffers bit rot, and probably falls over if you ever actually catch a big break) or go to iTunes and be a tiny undifferentiated speck in a sea of music, while paying 30% for the privilege. According to a couple reports I have seen, bandcamp is actually profitable. Maybe they won't be crushing the majors any time soon, but they seem to be proving there is a viable market for what small musicians do.
