I don't know about Omega Nutrition, Caitlin might. You can post a new message, I am sure someone will reply.
Caitlin talks about centrifuged Wilderness Family oil, I have yet to look into it.
It's easier to find better deals on internet as most are independant distributors and they have low overhead expenses. I always search for the item, I am looking for and then click 'froogle' on top (of google search).
