My vanilla lovers love Vanilla Select from Brambleberry. I have only used it in bath and body, but everyone loves it. All ages. Especially the young ones. Great in lotions, sprays, roll-on perfumes, bath bombs, etc.
If you are looking for perfume dupes like Shalimar, Opium, etc. it is the only place that I have found that has dupes that smell like the original. I am not a perfume fan, but a lot of my friends are. I have only used their scents for bath and body. Haven't tried them in my candles or cold process soaps.
If your soap is round to fit in the container, try using coffee filters. You need a 3 inch piece of PVC pipe. Put the soap in the filter in the pipe. It works great. Does not look like a coffee filter. It creases it and then you put the round sticker on it.
cottonblossomcrafts.com has very nice ones. My customers buy them. I sell a container with one soap wrapped like a small basket or as a set with brush and brush holder.
You have picked some good ones in Peak's and CS. I also like Brambleberry. They have some unique scents. Vanilla Select is the favorite of my vanilla lovers. Their Energy and Karma are very good also, as are many of their fragrances. I also like AH and Lonestar. I like too many. If you like cinnamon, try Celtic Spice from AH. It is great.
Sugar scrubs are more gentle. Salt scrubs are better at exfoliation. I use the salt on my feet. Of course, if you have cuts or cracks, even on your feet, you don't want salt.
When you order Spirit of Avalon from Moonworks, try Enchanted Spice. I use it for soap. Men love it. Women, too. I have had men order anywhere from 3 to 8 bars of it at a time.
