I submitted a small (15 or so images) batch to BNPS a couple months ago and pretty soon they showed a sale. So I added more and had a couple more sales. This looked like a promising start, so I included BNPS with the sites to which I usually upload any new batches to. After these initial sales, it just dried up. They started out promising but I guess it gets tougher and tougher to survive in this business.
