I think Frybrid.com has some members that offer free or cheap WVO if you are traveling.
I myself offer filtered/dewatered WVO for sale cheap to help cover the cost of filtering - when i have extra which at the moment i don't but should have soon. A guy i sold a tankfull to last fall just contacted me yesturday wanting to buy more (he has a 100 gallon tank) and I had to tell him all i could provide right now was about 30 gallons.
