Avocado oil is about 15x as expensive as vegetable oil. Other oils (including animal fats) have too strong a taste to be used in applications where a neutral oil is required (e.g. salad dressings, emulsions).
Unless you're deep frying everything, which arguably unhealthy regardless of chosen fat, it's hard to believe avocado oil is a significant component to meal cost. I just pan fried some vegetables, and I may have spent 5c on oil?
I'm with you. Even using the most expensive Avocado I could find at the Whole Foods in the smallest container I'd still only be spending $0.30 on a tablespoon, which is enough to cook a meal for 1-4 people in a cast iron pan. Doing this makes me feel a lot better than having to worry about the temperature of a teflon-coated pan.
They have both california sourced oil and a blend of international oils, I think the blend came out when they were having supply issues. They state it plainly on the label.
