PenguinSong.com is the moneygrubbing capitalist subsidiary of PenguinSong.net. The idea is to sell stuff -- CD's, shrink-wrapped software, T-shirts, guitar picks, and so on -- and to put the proceeds back into the coop's pool.

As with many coops (for example, REI, which sells camping gear), members and non-members would pay the same price for the stuff they buy. The difference is that members will get a rebate, representing their share of the profits.
