I'm in the Bay Area, too, and I don't know of any FO supplier in the area. I would say the closest would be Genwax in Hollywood. I've never used their oils so I can't vouch for them.
I also want to add that the cs from EBC is great. I called them because I had a couple of questions about their sale. I talked to Bill (owner, I think) and he was very nice and more than happy to box my soap and sprayers for the cheapest possible shipping. I received my order today (about 2 business days after placing order). Very please with cs so I hope the bases work well for me.
The pumpkin and mango sound interesting. Are there any actual benefits for the skin with these, or is it mostly for fun? I just ordered some bases and I can't wait to try different additives.
I know this won't answer your original question, but it's a suggestion for all that extra wax. I throw mine in a tin or thick glass bowl on my warmer. Requires no extra jars or work!
Definitely designer types, fruity, fun scents. I like fresh scents, but I don't want to smell like laundry. More like water blossom ivy, that kind of clean scent. No bakery. I don't make sprays so these are just my opinions as a consumer.
