Allow fans to pay £0 for releases

This has come up a few times in feedback from users. It's something that bandcamp supports and is seen as a powerful way to build a following on bandcamp. I've been a bit hesitant to implement it from the get-go as I'm not sure how much it would cost us. Perhaps we can put some policy guard rails on this?

• allow artists to enable £0 purchases for a given album
• allow users to specify £0 at checkout
• only allow this if they also sign up to the artists mailing list
• work out how much it actually costs us to offer this (I think Stripe supports zero-price purchases but I don't know if they charge. Bandwidth costs are probably fairly cheap)
• Have a policy which says "if you sell more than X zero-cost downloads we'll deduct X from your future purchases").

Zero-cost purchases seem to work without us doing anything - Stripe automatically supports them. Longer term we might want to tackle some of the things above (e.g limits on the number or enforcing signup to the mailing list) but we can come back to it. I'm going to close this now.
