Bring your own reusable bags to Whole Foods and get a 10 cent credit for each bag. Plus you're helping the environment at the same time! Love it!

In addition, you can bring your own containers from home to fill with stuff from the bulk bins. Just go to CS when you arrive and have it weighed. I always have a white label on my container to write the weight (tare) and the item #. This way I don't have to transfer flour or rice from a plastic bag to my container when I get home. They do not give you credit for using your own container, though.
