Like Heather said, try to find the heavy stuff like wax near you. If you can pick it up, all the better. Wax, wicks, containers and other accessories will all be pretty comparable wherever you get them so price and shipping should be the main considerations. When it comes to FO, quality is the main concern. Everyone on this board will have their favorite suppliers and the list will become long. My personal preference is Just Scent followed by Peak. Also remember that what works for some people doesn't always mean it will work for you with your combination of wax, wick & FO. IMHO
