Everything is more expensive these days, it seems, and shopping the sales only helps so much. If you're like me and try to buy natural or organic products when possible, it's even more expensive as they rarely go on sale at the grocery stores.

A great way to save money and increase selection is to start up a cooperative buying group. We've started two and here's how you can start one, too!
