We just buy the Whole Foods standard bottle - and it lasts us a year (we actually cook most meals - so not a lot of oil being used). I do use butter too - in moderation. No pre-processed butter food products for me, thank you

Interesting on the coconut oil - I'll have to explore. I think it may be hydrogenated coconut oil I've heard all the bad stuff about (but I was thinking coconut milk too).
