I was at Whole Foods Market (4800 El Camino Real, Los Altos, CA 94022 Phone: 650.559.0300) yesterday and I was in the beauty section of the store. I looked at the Aura Casia essential oil shelf, I found that Aura Casia is selling Sweet Almond, Grapeseed, Jojoba and Apricot Kernal Oils in 8 to 16 oz at this location. They are rather on the expensive side but if you cannot get to another retail establishment that sells these types of products, you can purchase them here. I have not seen these products offered at the other locations (ie Redwood City), but you can surely ask.
In the same section, Whole Foods sells Castor Oil, Liquid Lanolin and Vegetable Glycerin.
By the way, Whole Foods does carrier Avocado, Walnut, Almond and Grapeseed oil in their regular Oil/Vinegar aisle.
Of course, they also sell essential oils from Aura Cacia and Oahdashi.
So if you are looking for particular carrier oils or glycerin for your lotions or other body products check out Whole Foods for some of your supplies/ingredients. For other Whole Foods Market locations, check out their website at http://www.wholefoodsmarket.com/.
