The business model of Bandcamp.com is, in my opinion as a consumer of music and someone who believes in purchasing music, an excellent one to ensure that artists get most of the revenue for their work and consumers get a fair price. The work required to create a music sharing platform is significant so I believe that 10%-15% of the revenue is a fair price for the middleman who makes all of this possible. The artists have complete control to put a price on their music they feel is fair market value, and to offer bulk purchasing deals for consumers who really dig their music and would like to own it all. I can't think of a better way to compensate artists fairly and treat customers fairly as well.
In terms of how the site works it is very simple to use. The terms and conditions are clear as are the instructions for use. I have purchased many original works on this site and I have never had an issue with the payment process or any significant technical problems with the site itself. I have found that Firefox seems to work better than Chrome but other than that I have not observed any technical, payment or process issues.
I hope this helps anyone who is considering using the application. In summary the reason I support it so strongly is the knowledge that the artists are receiving 85% of the revenues. We cannot as a consumer base expect artists to create fabulous content and then not compensate them fairly for their work. That's why I chose Bandcamp.com over other sites such as YouTube Music Spotify and Amazon where there is controversy over whether the artists are being fairly compensated and in some cases have claimed they cannot make a living wage.
