I made a soap with it a while ago for shaving. I haven't used it yet, but it was easy enough to work with. I have seen avocado oil on sale at costco last few times I'm there. It might be a good place to get it they also sold coconut oil. but it was Extra Virgin Cold Pressed, which I like for eating but is a waste for soap.
For coconut--i use Louanns for soap, and organic stuff for food.
I'm not sure if there is a "discount" brand, or if all avocado oil is going to be premium.
