I am looking out for those who have already done it. I bought the figures from the comic by @katharsisdrill. I don't know how well that limited edition sold.
There are so many bands with a small, dedicated following who already do a lot on-line. People have to be technical enough to deal with Facebook, Bandcamp etc. I mentioned Steem to Steve Lawson, but he is doing his own thing. Just needs someone to take the risk on it.
