The only thing I really don't like about Bandcamp is their lack of an API and the consequent difficulty of automatically downloading purchased albums.

But what's even worse is that their CDN throttles your IP after ~15 downloads and you have to wait 1-2 hours before you can download again (which I've already hit a few times, even while clicking on the links manually)
Granted, that means still a third step to orchestrate - auth ending in cookie capture, then album list fetch and reconciliation, and finally (on the other end of some queue) album downloading. Thank goodness they didn't make it too simple, I guess - I'd have hated for their annoyingly inconsistent login captcha to have been the last arbitrary challenge I had to overcome.
(I can't fairly give them too hard a time, I suppose - they're doing an incredible amount with a tiny team and in that context even having pulled their public API is reasonable, however much I wish they hadn't. Just that it'd be nice if they had the scope for dealing with use cases that aren't the adversarial mirroring they've clearly optimized against...)
