Geez, I don't know. I see a lot of people on the net pushing their shit and they can't seem to get off 100 Cd's. Everybody bragging about how many units they pushing in the underground, but the part they never tell us is, out of 1,000 copies. They only sold 50 and gave the rest away in so called promotion.
BUT!!!! I see what you are saying, though and you right. Most underground artist today are still unaware that it's a digital world in the music biz.
Artist pushing Cd's in the street and putting them in local Mom & Pop's stores etc etc..... is limited compare to how much more they can push online.
