Need Your Opinion

I am considering starting an aromatherapy club in my hyenacart store and was wondering if anyone had an opinion on it. I was thinking of having 3 month, 6 month, and one year options. I was thinking about doing some awesome oils too like petitgrain bigarade (which smells very neroli-like) and yuzu along with some of the other more basic oils. The first month would of course be Lavender (high altitude French Lavender) because, I believe everyone should have lavender in the house, anyway-it's good for everything. I was thinking of doing the educational info on index cards so my customer could file them and offering a product every month that is made with the featured oil. I was also thinking that I could send out previews for new products. Any thoughts?
