Hi
I've used Essentially Oils for 10 years now - met Charles, (..briefly!) he's a nice chap, and so is Jan, his wife. (although a lady, not a chap!)
They are brilliant to deal with, and, as has already been mentioned, they have a monthly newsletter whcih has special offers on.
If you are after something special that you cant get anywhere else - RING THEM - you may be surprised, they may stock it, or be able to source it for you.
No, they are not cheap. There are cheaper suppliers out there, but the service and quality is 2nd to none!!
Hope this has helped!
