I'm going to be the descending vote. I don't think their prices are a direct reflection of quality or concentration. I don't think anything I tried from them was better than what I got from FB. I used their fragrances few years ago and they were hit or miss for me. I didn't keep detailed notes but I'll contribute what I have.
Acorn & Oak Leaves: didn't smell like fall to me. It smells heavily perfumy and sticks very well. I'm not sure how to describe it. It is too heavy for me but I have a number of people who looooooved it. Next time, I'm dropping the usage rate to 2.5% ppo or even less. I think this is an FO that will make a great blender.
Honey Harvest: this is nothing like L'occitane's Honey. It has a definite bitter almond note. It is also strong and survives cp well. As much as I dislike bitter almond, I find that I can tolerate this FO. Several people ask for it. I ended up pouring the leftover HH on top of the leftover A&OL in small flower molds. Those bars disappeared first. I have bars from both of these that are about a year old and both are still strong.
Bergamot & Chamomile: This one is not very strong and doesn't smell like much OOB or in a dry soap. When wet, it becomes a clean lovely scent. Holding well at over a year. I love it. It is different than BB's Bergamot&Chamomile. I ended up hoarding the bars I made with it for me. They also were the first bars I made with added canola. Who would have guessed that canola from Costco is a luxury oil?
They had an unusual scent called Sake that I liked and it's now gone. I also tried Hydrogen, Citrus and Basil and ended up mixing the 2 for a guy FO. I have to look at what else I tried and update.
I'm planning on placing an order for the 3 FOs above and add Green Tea and their version of L'occitane's Linden. I'll be looking at the recommendations in this thread to add few testers to my order.
