The Healthful Pantry - is a great co-op that has been up and running for a little while. The aim is to provide organic pantry goods at fairly competitive prices. The have a huge list of products they supply. You order what you want and then they collate all the orders, buy in bulk at discount prices and then you pick up your goods. They usually do an order about once every six weeks so a little bit of forward planning is needed. Plus if they don't stock what you want they'll try and find it for you anyway. Check it out!

The other co-op I know of is the 'Beanstalk organic food co-op'. They supply a weekly fresh fruit and veg box as well as dairy & meat. I found they had good stock, by the only downside was you had to pick up from Mayfield on a Tuesday arvo/evening which was a little unsustainable for me.
