Just an Idea, probably just a gimick- but for those who have digital labels, why not sell your wares on USB flash drive?
Consumers get top notch music on a flash drive that will in the long run always come in handy.
I found a site that sells in bulk and will even print your name on the shell of it.
Actually, it would be kind of cool promo for the nights that you play/run...
Just an idea anyway. Probably silly innit.
