Be careful using the ziplock bags, as they suck out the FO some how. I started using cello bags. They sell some ziplocks that are ok, I think they are called polypro. Alot of people use the little shoe box containers with a 5 on bottom for storing leftover wax etc. Just make sure you use seperate ones for each scent. All StateFarms seem to be different from State to State. We use them for our home and cars, have been very happy with them:)
