I sell 15+ EO, scent free, and coffee soaps. They all have the same basic Olive Oil, Palm Oil, Coconut Oil, Castor Oil, and Shea Butter formula. The biggest seller, year round, is Lavender. Next is Sweet Orange, Peppermint, Lemongrass, Eucalyptus, Tea Tree w/Charcoal, Turmeric w/Turmeric Powder, and Coffee. Finally Patchouli, Scotch Pine, Cedarwood, Tea Tree, Palmarosa, Ylang Ylang, and Scent Free. I've made Rosemary and Frankincense but I stopped due to poor sales. I hope to add 3 more scents in the near future. I have found that having a large variety of soaps has a direct and significant positive impact on sales.
