I think that's just silly you won't buy it off of like CD Baby which is as cheap as I'll go with the album. I actually make most of the money off of the iTunes sales as well as the CD Baby sales. Additionally I'll be signing up for CD Baby Pro which basically gives me all the royalties because I wrote every song.
Now, maybe I will upload it on BandCamp but getting it on places such as iTunes, Amazon, and Spotify (even though I hate Spotify) gets it more attention because it sounds more official. I'm serious. That's one of the reasons I do it. It's just "cool" to have it on iTunes or Spotify or CD Baby and if it was BandCamp-only, there are some people that don't find that "legit". Also, I'd like to eventually sell hard copies and CD Baby can develop them for me. Not sure if BandCamp does that or not.
However, I may consider getting it on BandCamp, because you're not wrong. It's a good deal. And it's really popular too. But it also doesn't come off as "legit" as iTunes does. You can find that funny but I'm serious.
EDIT: You're gonna get what you want. xD I'm just gonna upload it to BandCamp now.
