Damn 3tbsp a day. That's gotta work out to be pretty expensive huh? Seems to be one of the cheaper oils though compared to others that are healthy. I was looking into bulk olive oil purchases, but read that most olive oils are diluted and not 100% pure. There are a few websites out there that do studies by purchasing olive oil, taking it to a lab and testing it's quality/purity. I think walmarts brand seems to be up in there air on quality, costco seems to be legit though, but I don't live near one
.
Mountain Rose is the cheapest source Ive found. It's 'refined' organic coconut oil @:
1gal(128oz) = $32 + $16.74 shipping = $48.74 ($0.380 per oz)
5gal(640oz) = $136 + $47.75 shipping = $183.75 ($0.287 per oz)
Sucks because some people say you need unrefined for certain things like applying on skin and eating, but cooking/oil pulling seems to okay w/ any.
Going to have to look into that a bit deeper. Unrefined is damned expensive.
Not sure what you're paying, but nuts.com sometimes has good prices on stuff:
http://www.nuts.com/search?q=Pistachio (they have a bunch of different types)
Better buying in bulk since most things you probably wont save much when shipping prices are factored in.
You can also get pistachio oil for around $12 per 8oz @ some sites. Not sure if this is cost effective or not though, since it's around $10 per 1lb w/o shells @ some places.
Just depends on how much oil can be extracted from a 1 lb bag of pistachios. Doubt it's anywhere near 1 lb since there are also other contents of the nut that wouldn't make an oil and would have to be filtered out.
