BNR/Ss can be helpful if they match your goals. When I first started out my sales were very small, but I noticed that they increased as I was involved in several BNR's, even getting sales outside of the BNR. But for me, those did not generate regular customers. I then started getting involved in BNS's and found a small nitche market. Right now I am involved with 1 or 2 BNS's only because they usually have people on the treasuries that have items that I need for my branding, so it makes it profitable for me to be involved. Some times I don't have any sales, and sometimes I may get 4 sales out of a BNS. Personally, I think it depends on the products you sell, and the products you purchase and if they are worth it to you.
