Yes the price difference of coconut oil, avocado oil and olive oil are really not much different. I personally don't use olive oil for cooking things at high heat because the smoke point is lower...but I will often drizzle some over whatever I cooked at the end for that flavor. I will use it when making a nice tomato sauce that I'm simmering for hours, or in soups, etc I just try to be careful with the temp when I am browning/sautéing veggies/potatoes and such because I just don't want things to burn. I would say, if you aren't having issues with burning using olive oil currently, then I can't see a reason to switch.
