DeviantArt has always been a nice community. I find it surprising that the price is so low given that they add a lot of value.
Having moved in Deviant Art circles (some time ago, admittedly) I'd say one reason for the low price might be that, somewhat like Reddit, the core values of the community make it challenging to monetize.
I also can't imagine the print-selling business reaching the kind of scale that today's VCs would like to see.
