The first CO I ever bought was Spectrum Naturals UNREFINED, which they sell at most health food stores. (They also sell a refined version, which is not what you want). I was very pleased with it, and it came in a 1 pint jar I believe. It's organic and expeller pressed. I now use Tropical Traditions (b/c they were having a sale and I bought a gallon), which I also like, but I plan to keep trying different brands.
Coconut milk contains coconut oil, in varying amounts. Most of what's sold is pretty rich, so you should get some of the benefits of the oil if you drink enough of it.
