Niggles: ...
Didn't they have limited downloads (of purchased albums) sometime in the past (not the code business) - is that still an issue?.
In the past, yes - also if you don't have fan account.
However, it is possible to obtain a new download link.
With fan account I don't have to worry about expired download links.

Contact with customer support...?
One mistake... Bandcamp is not a shop (at least not typical). It works like Humble Bundle Widgets (not Humble Store), but with more features (such as main site with searching). Is entirely dependent on artists of what is available and what prices (also your payment goes directly to artists). Some downside: if artist or label delete their account, files also disappear (customer/fan can't re-download).
