Reuse containers and save some $$$.
I might be the last person in the world to discover this, but I'm sharing it anyway...just in case. I recently refilled my little bottle of Dr. Bronners soap (if you're unfamiliar http://www.drbronner.com/drb_soapsandingredients.html) at my local co-co (PCC in Seattle) and it was only $1.32 for the refill versus about $2.50 for a new bottle. They had a lot of different products that you could buy in bulk like that and it seemed way cheaper to me. P.S. I also recently discovered that it's WAY WAY cheaper to refill spices from the bulk section too. Spices are sooo expensive to buy in new bottles. Sorry if everybody already knew this.
