FO sampler packs is the way to go to check out a new supplier -or- to just check out new FOs you haven't used before and dying to try out. Most of us use several suppliers and may have more than one fav supplier. Maybe C&S FOs work for you but do nothing for my candles. I have used a couple of their FOs in soap that work well though. So it also depends on what treatment you are doing-- candles, soap, what wax, what soap process, butters, oils, wicks, jars, the list goes on and on. If you are near C&S have you also looked at Candlewic? You may be close to them and could try a sampler pack from them. When it comes to FOs I want the best so I try samples from lots of suppliers all over. On the other hand, my wax, jars, and heavy stuff I try to find more local suppliers to cut down on shipping costs.
