Citizen's Co-op now has 232 members, and if you follow them on the Twitter you can keep up with the latest news. They are also on Facebook and they really should post a link so people can follow them there, as well. Oh well, guess I just did!
Anyway, here's my idea: As part of the co-op bulk section (and you know they're going to have one) they should include things like bulk laundry soap (I suggest Charlie's), Dish soap, and plain organic castile soap (which you can get in drums). People could bring their own containers and buy it by the ounce or pound. That's it -- simple, elegant, and saves on packaging.
